Documentation Standard
Each lot is supported by:
- Identity confirmation — mass spectrometry verifies the molecular identity of the lot.
- Analytical purity — high-performance liquid chromatography (HPLC) confirms ≥99% analytical purity.
- Lot number — printed on the vial and shipping documentation, tying each unit to its archived analytical record.
- Certificate of Analysis (CoA) — per-lot summary of identity, purity, test methods, and release date, available on request.
CoA Access
Qualified research customers may request a Certificate of Analysis for any lot at any time. Include your order reference and lot number when contacting support at coa@retron.bio.
Sample Certificate of Analysis
A representative Certificate of Analysis is available below in PDF form. It illustrates the lot-level documentation format Retron Labs maintains for every released analytical reference material lot — identity confirmation by mass spectrometry, ≥99% analytical purity by HPLC, water content, endotoxin testing, and analyst/QA signatures.

Method References
HPLC analyses are performed using validated reversed-phase methods appropriate to each compound class. Mass spectrometry uses electrospray ionization on appropriate instrumentation. Methods are documented and traceable per lot.
Material Handling Reference (Laboratory)
Lyophilized reference materials should be handled in a controlled laboratory environment. Maintain materials in their original sealed vials until use in your analytical workflow. This page is a reference-material documentation page only and does not provide use, administration, or human-use instructions of any kind.
