Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide high-purity material suitable for research and development, with typical purity levels exceeding 95% (by HPLC). Certificates of Analysis (COA) detailing chiral purity, chemical identity, and impurity profiles are available upon request. Our quality system is designed to support cGMP and ISO guidelines for reliable and traceable material supply.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at a controlled room temperature (15-25°C). This material is light-sensitive and easily oxidized; prolonged exposure to air and light should be avoided to maintain stability and purity.
