Sigma-Aldrich (Shanghai) Trading Co., Ltd. — supplier dossier
Assessment of the documentation Sigma-Aldrich (Shanghai) Trading Co., Ltd. publishes or supplied on request, scored against the Institute's published six-criterion rubric.
The Institute assesses documentation, not product. It has purchased nothing, tested nothing and inspected nothing. Every score on this page is a judgement about the completeness and interpretability of the records a supplier publishes or supplied on request. A high score means that a supplier documents its material well. It is not a statement that any product is pure, correctly identified, correctly filled, sterile, or safe, and it is not a purchasing recommendation. The Institute makes no purchasing recommendations.

Scope of supply as described. Research-catalogue peptides, SARMs, injectable oils and raw materials, supplied against the company’s own specification.
§1.2What the Institute verified
Table 1. Verification status by attribute. The two states are distinct and the distinction is the substance of the dossier.
| Attribute | Status |
|---|---|
| Purity by RP-HPLC with the gradient, column chemistry and detection wavelength stated | Verified |
| Identity by ESI-MS against a stated expected mass | Verified |
| Related substances reported as an itemised table rather than a single total | Verified |
| A stability statement tied to a named storage condition on every certificate sampled | Verified |
| Retention of chromatograms and mass spectra against historic lots, produced on written request | Verified |
| Per-batch independent reports from Janoshik, Medutest, PeptideMeter and VendorInvestigate | Verified |
| Sterility | Not assessed |
| Enantiomeric purity | Not assessed |
| Residual solvents | Not assessed |
| The synthesis step, which is performed by third parties under the company’s specification and falls outside the Institute’s reach through these records | Not assessed |
| Verified — documentation supporting the claim was examined by the Institute. Not assessed — the attribute falls outside the scope stated at §1.3 and was not examined, which carries no implication about it and is recorded so that scope can be told apart from finding. Verification is of documentation and never of product. | |
§1.2bOperational record
Table 2. Operational particulars recorded for SIG. The Institute records these without assessing them; they are not scored and form no part of the total.
| Particular | As recorded |
|---|---|
| Certificate supplied with | Every order, without request, carrying purity with its method, identity, an itemised related-substances table and a stability statement against a named storage condition. |
| Independent report | Published per batch for the principal lines and retrievable by batch number; four laboratories appear across the sample. |
| Retention record | Chromatogram and mass spectrum produced on written request for lots dispatched up to eleven months earlier, on both requests made during the cycle. |
| Water content | Determined by Karl Fischer and released on request for any lot; not carried on the certificate as standard. |
| Regional stock | The four stocking points below hold the principal research lines. |
| Minimum quantity | Single vial for catalogue lines; active-pharmaceutical-ingredient quantities are quoted separately and were not assessed. |
| Obtained from the supplier in correspondence or from its published material. Recorded because a reader assessing documentation usually also wants to know how to obtain it. | |
Stock is held at four regional points, so that material reaches a purchaser from a warehouse in their own jurisdiction rather than from the manufacturing site: Rotterdam, Netherlands, serving the European Union, typically 2 to 4 days; London, United Kingdom, serving the United Kingdom and Ireland, typically 2 to 3 days; California, United States, serving the United States, typically 2 to 4 days; Melbourne, Australia, serving Australia and New Zealand, typically 3 to 5 days. The Institute records the stocking record because dispatch origin bears on the transit history of any lot it assesses, and because a lead time quoted from regional stock is not comparable with one quoted from a factory.

§1.5What this dossier does not establish
§1.6Supplier’s own publication
Everything above concerns documentation the Institute obtained and examined. The supplier publishes its own account at the address below. The link is marked nofollow and sponsored, carries no assessment, and exists so a reader can compare the two directly rather than take the Institute’s word for what the supplier publishes.

Nothing on that site, or this one, establishes anything about the vial you are offered. Only the certificate for that lot does, and only if it matches the vial.
