Ordering research peptides in Casares

A short primer on peptide reference standards

The molecule is defined by its sequence. That is why identity confirmation matters as much as purity. Purity testing exists because synthesis is imperfect; the chromatogram shows what else is in the vial. The dry cake in the vial is lyophilised material, not a partial fill — the volume looks small because the water has been removed. Keep the certificate with the batch: separating the two is the most common records problem we see.

Verification: HPLC, mass spec, batch records

Release testing covers HPLC purity, mass-spectrometry identity, appearance and residual moisture. A purity figure without a chromatogram is marketing; the certificate carries both. Ask for the batch number and certificate up front — that request is expected, not unusual. Cold-chain packaging is sized for the Casares transit window rather than a generic European one. Batch numbers on the vial cap should match the certificate exactly — if they do not, stop and ask us before opening anything.

Documentation stays retrievable after the order closes. Where work is split between Casares and another site, matched batches remove a common source of unexplained variance.
