A transparent, documented chain for every research compound we list.

1

Synthesis & lot ID

Each production lot is assigned a unique batch number recorded against its raw materials.

2

HPLC purity

High-performance liquid chromatography quantifies purity against the ≥98% release threshold.

3

MS identity

Mass spectrometry confirms molecular mass matches the expected sequence for the compound.

4

COA published

The signed third-party certificate is published here and searchable by batch number.
