Quality
Testing and documentation
Reliable research depends on knowing exactly what is in the vial. Every lot we distribute carries independent analytical documentation tied to the lot number on the label.
01
Synthesis and controlled fill
Materials are produced under documented process controls, sterile-filtered where applicable, and lyophilized into single-lot fills with recorded fill weight.
02
Independent purity analysis
A retained sample from each lot is submitted to an independent laboratory for HPLC purity determination against our published specification.
03
Identity confirmation
Mass spectrometry confirms molecular identity and expected mass for the lot before release for distribution.
04
Documentation and release
The certificate of analysis is matched to the printed lot number, archived to your account, and included with the shipment.
