What’s on every COA
Each Certificate of Analysis documents the product’s identity and the analytical results for that lot against a defined specification. Every item below appears on the certificate for the batch you look up — supplied for laboratory research use only.
Product identity
Product name, CAS number and PubChem CID — unambiguous identification of the compound.
Molecular data
Molecular formula and molecular weight, with identity confirmed by ESI-MS.
Appearance
Colour and physical form against specification — white to off-white lyophilised powder.
Purity
Chromatographic purity by reverse-phase HPLC, reported as area percent.
Related substances
Total related substances and the largest single impurity against defined limits.
Counter-ion (TFA)
Residual trifluoroacetate remaining from synthesis and purification.
Water content
Residual moisture in the lyophilised powder by Karl Fischer titration.
Residual solvents
Acetonitrile, DCM and DMF screened by headspace GC against ICH Q3C limits.
Microbial safety
Bacterial endotoxins and bioburden screened, as applicable.
Frequently asked questions
Where is my batch number?
Each vial is labelled with a batch (lot) number in the format OP-XXXXX. One batch number corresponds to one manufactured lot.
Why is email verification required?
Batch documentation is released to customers of record. Verifying the email associated with your order confirms eligibility; the address is not displayed or shared.
What does the certificate report?
Product identity (name, CAS number, PubChem CID), molecular formula and weight, appearance, HPLC purity (≥ 98.5%), counter-ion (TFA) content, and recommended storage — each result against its specification.
The batch number returns no result.
Confirm the value against the vial label. If unresolved, contact Customer Support with your order reference and the certificate will be issued directly.
