Certificates of Analysis.
Verify a batch
Every vial carries a batch number on its label. Type it here and you get the certificate issued for that exact lot — 10 are published right now.
Every published certificate is listed below, by compound. A certificate names one production lot. If a supplier shows you a single document covering every batch they have ever sold, it is a marketing sheet, not a certificate of analysis.
A Certificate of Analysis is the laboratory report that travels with a specific production batch — every test that batch was put through, the specification each test had to meet, and the result actually measured.
Certificates by compound
One entry per compound in the catalog. Where a certificate has been issued for the current batch it can be opened below; the rest are added as each lot is released.

What a certificate is, and why it names a batch
A certificate is only meaningful when it is tied to a batch number. Purity is not a property of a compound in the abstract; it is a property of one lot of material made on one day. That is why every certificate above names its batch, and why we publish them per lot rather than as a single generic document.
Each report is signed and dated by the analyst who ran it, and states the method used alongside the result — so a figure can be checked against the technique that produced it rather than taken on trust.
All material is supplied for laboratory research use only. Certificates are provided so researchers can verify identity, purity and residue limits before use.
What each test means
Our certificates report the following. Not every compound is assessed against every line — small molecules and ancillaries carry a shorter panel than peptides.
Identity — is it the right molecule?
- Appearance
- A visual check of the lyophilized powder against the expected description. Colour or texture that does not match is the first sign something is wrong.
- Solubility
- Confirms the material dissolves as it should in the stated solvent. Poor solubility can indicate degradation or the wrong salt form.
- Solution clarity and colour
- The reconstituted solution is examined for haze or tint at a set concentration. Cloudiness points to insoluble impurities.
- Identification — HPLC
- The retention time of the main peak is compared against a reference standard. Matching retention time is evidence the principal component is the compound named on the label.
- Identification — mass spectrometry
- Measures the molecular weight directly and compares it to the theoretical value. This is the strongest single confirmation of identity.
- Amino acid content
- The peptide is broken down and each amino acid counted against the expected ratio. It confirms the sequence composition rather than just the total mass.
Purity — how much of it is the compound?
- Purity (HPLC)
- The share of the total chromatogram area belonging to the main peak. This is the headline purity figure, typically specified as not less than 98%.
- Related substances (HPLC)
- Measures impurities related to the peptide itself — truncated or modified sequences. Both the largest single impurity and the total are limited.
- Oligomer
- Detects peptide chains that have joined together into dimers or larger aggregates, which behave differently from the intended molecule.
- Peptide content
- How much of the vial contents is actually peptide, as opposed to counter-ions, water and salts. A vial can be 99% pure yet contain less peptide than expected.
- Assay
- The quantitative measure of active substance, calculated on an anhydrous, ion-free basis. This is what confirms the stated milligram amount.
Residues — what else is in the vial?
- Acid group ions (TFA / acetate)
- Peptide synthesis and purification leave counter-ions behind, most often trifluoroacetate. The certificate limits how much remains.
- Residual solvent
- Screens for solvents used during manufacture — acetonitrile, methylene chloride, MTBE, DMF — each against its own limit.
- Water content (Karl Fischer)
- Moisture in the lyophilized powder. Excess water shortens shelf life and makes the mass on the label less accurate.
- Sodium ion
- Residual sodium from buffers and purification, reported as a percentage of the total.
- pH
- The pH of the reconstituted solution, which affects both stability and how the material behaves in solution.
Microbiological safety
- Bacterial endotoxins
- Measures endotoxin (pyrogen) load in endotoxin units per milligram. Endotoxins survive sterilisation and are tested for separately.
- Microbial limits
- Total aerobic bacteria and mould/yeast counts, plus absence testing for bile-tolerant enterobacteria, Pseudomonas aeruginosa and Staphylococcus aureus.
Handling
- Storage
- The conditions the batch was qualified under — sealed, protected from light, at the stated temperature.
- Batch and retest date
- Ties the certificate to one specific production lot and states when that lot should be re-examined.
