Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized to confirm identity, purity, and chiral integrity. Certificates of Analysis (COA) are available upon request, detailing specifications such as assay (HPLC), chiral purity, and impurity profiles. We adhere to a cGMP-compliant quality management system for traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation and moisture uptake.
