Amino Axiom is a free research information and tracking platform that sits alongside the vendor network this brand belongs to. Its vendor status tracker records which research vendors are defunct, the reason given for each, and a timeline of FDA enforcement actions that relate to the research-compound market. The tracker is at https://www.aminoaxiom.com/vendor-status.
This FAQ covers what the tracker shows and how a researcher working with small molecules can read it when planning a project. It is about reading records, not about any use of the materials. Everything here is for research purposes only.
Why would a small-molecule researcher care whether a vendor is defunct?
Research projects run for months. A compound ordered in one quarter may need a matching lot in the next, and a protocol that depends on one source can stall if that source disappears. Continuity of supply is a real part of experimental design, because switching vendors mid-project introduces a new variable: a different lot, possibly a different salt form, and possibly different impurities.
A status tracker lets a researcher check the standing of a vendor before building a plan around it, and check the standing of past sources when a record needs explaining. It is a due-diligence aid sitting next to price and profile information.
What does the tracker show for each vendor?
Each entry identifies a vendor that is no longer operating and gives the reason recorded for it. Reasons vary. A vendor may have closed voluntarily, been shut down following an enforcement action, or simply stopped responding. The entry states what the platform displays and nothing more. This article makes no claim about the completeness or accuracy of those entries beyond what they visibly say.
A researcher should read the reason field as context for risk. A voluntary closure and an enforcement-related closure imply different things about how orderly the wind-down was, which in turn affects whether any outstanding documentation for past lots can still be obtained.
What is the FDA enforcement timeline?
Alongside the vendor entries, the tracker shows a chronological timeline of FDA enforcement actions touching the research-compound space. Reading it in order gives a sense of how regulatory attention has moved over time: which categories of product drew action, and roughly when.
For a small-molecule researcher, the timeline is background rather than instruction. It helps explain why the vendor landscape looks the way it does and why some listings disappear. It does not say anything about any individual compound's suitability for research, and it is not legal advice. An institution's own compliance office remains the authority on what a given lab may purchase and hold.
How do the three catalog compounds relate to it?
The brand catalogs three small-molecule research compounds, and each illustrates a different way to use the tracker.
AICAR is a long-established tool compound studied in AMP-activated protein kinase (AMPK) pathway models. Because it has been sold for a long time, it has a long supplier history, and some past sources will appear as defunct. A researcher tracing the provenance of an older lot can check whether the named source still exists, which affects whether supporting records can be requested.
SLU-PP-332 is a newer synthetic small molecule studied in connection with the estrogen-related receptor (ERR) family. Its supplier history is short. For a young compound the useful check is forward-looking: whether the few vendors listing it are currently operating and have a stable record.
5-Amino-1MQ is a small-molecule inhibitor studied against nicotinamide N-methyltransferase (NNMT) in cell-based metabolic models. It sits in the middle in terms of history. A researcher can use the tracker to confirm that a given source has not appeared among the defunct entries before committing to a multi-month assay series.
How should the tracker be used alongside the vendor directory?
The tracker and the directory answer different questions. The directory describes vendors that are active: payment rails, compound counts and ratings. The tracker describes vendors that are gone, and why. Read together they cover both ends of a vendor's lifecycle.
A reasonable order for a researcher is:
Identify candidate vendors for the compound needed.
Check each against the status tracker for any entry.
Read the active profiles for fit with institutional purchasing.
Request lot-specific documentation from the remaining candidates.
The fourth step is the one no platform can do for the researcher. The lot's HPLC and mass-spectrometry records are what actually describe the material, and the brand's article on research compound sourcing documentation sets out what those records should contain.
What does a defunct vendor mean for material already in hand?
A lot purchased from a source that later closed is still the same lot. Its identity and purity are properties of the material, not of the vendor's present status. What changes is the researcher's ability to ask follow-up questions, such as requesting a corrected certificate or a retained-sample analysis.
This points to a record-keeping habit: when material arrives, file its documentation with the project immediately, rather than relying on the vendor to supply it again later. For small molecules, where identity is confirmed by mass spectrometry, the brand's article on interpreting mass spec data explains how to check the batch record against an expected molecular weight. If the original source later turns up on the tracker, the project already holds what it needs.
How should a researcher record what the tracker says?
The tracker is updated as events occur, so a statement that was true when a project began may not be true later. Record the vendor, the date the tracker was checked, the status shown and the link. Dated records make it possible to show, in a later review, that the standing of a source was checked at the time of selection. An undated note leaves that unanswerable.
Which catalog facts help trace a lot back to a source?
When the tracker shows a source as defunct, the material already in hand is still identifiable by its own properties. These catalog identifiers give a fixed reference to check a retained batch record against, as of October 2026.
AICAR: molecular weight 258.23 g/mol, CAS 2627-69-2.
SLU-PP-332: molecular weight 393.37 g/mol, CAS 2155854-26-3.
5-Amino-1MQ: free-base molecular weight 159.21 g/mol, CAS 42464-96-0.
A batch record whose stated weight or CAS number differs from these values describes a different form and should be queried while the question can still be answered. Filing the record with the project at receipt, as described above, keeps that check possible even after a vendor closes.
What are the limits of a status tracker?
Three limits are worth stating plainly:
It is a secondary source. An entry summarizes an event. It is not a primary legal or regulatory record, and a researcher who needs the primary record should locate it directly.
Absence is not endorsement. A vendor that does not appear on the tracker has not been shown to be in good standing. It has only not been recorded as defunct.
It lags events. A vendor can stop operating before an entry exists.
Used within those limits, the tracker is a quick check that adds one more fact to a sourcing decision. Used beyond them, it turns a missing entry into a false reassurance.
Where do the other Amino Axiom features fit?
The status tracker is one feature among several. The vendor directory, price comparison, the compare tool, the glossary and the compound library are separate, and this post covers only the tracker. Researchers who want to view it directly can start from the Amino Axiom homepage or go straight to the vendor status tracker.

Common questions
The tracker records which research vendors are defunct, the reason recorded for each closure, and a chronological timeline of FDA enforcement actions touching the research-compound market. It displays what the platform shows and nothing more, and it is not a primary legal record. For research purposes only.
Research projects run for months, and a compound ordered in one quarter may need a matching lot in the next. If a single source disappears, switching vendors introduces a new variable such as a different lot, salt form or impurity profile. Checking vendor standing first supports continuity of supply.
No, absence is not endorsement. A vendor that does not appear has only not been recorded as defunct, and the tracker can lag real events because a vendor can stop operating before an entry exists. It is one extra fact in a sourcing decision, not a reassurance.
The lot keeps its identity and purity, because those are properties of the material and not of the vendor's status. What is lost is the ability to ask the source follow-up questions, such as for a corrected certificate. Filing the batch documentation at receipt avoids depending on that.
The directory describes active vendors through payment rails, compound counts and ratings, while the tracker describes vendors that are gone and why. Read together they cover both ends of a vendor's lifecycle. A sensible order is to screen candidates against the tracker, then read active profiles.
