- 01
Synthesis & lyophilization
Compounds are synthesized by solid-phase peptide synthesis, purified by preparative HPLC, and lyophilized into sealed vials under nitrogen.
- 02
Independent sampling
A randomized sample from each lot is sent to an independent third-party laboratory such as Janoshik Analytical or Freedom Diagnostics. We never test our own material in-house for release.
- 03
HPLC purity
Reverse-phase HPLC at 220 nm quantifies purity. We require ≥98% for release; most lots exceed 99%.
- 04
Mass spectrometry identity
ESI-MS confirms the observed molecular weight matches the theoretical mass within ±1 Da, verifying sequence identity.
- 05
Publication
The full certificate is published on the product page and in the gallery above, matched to the batch number on your vial label. Where the lab offers it, a verification key lets you confirm the report directly with the lab.
