Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is analyzed using advanced techniques like HPLC, GC, and NMR to confirm identity, purity, and chiral integrity. Certificates of Analysis (COA) detailing all specifications are available upon request. We adhere to a cGMP-compliant quality management system to ensure traceability and consistency for research and development applications.

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 compound is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); therefore, containers should be purged with an inert gas (e.g., nitrogen or argon) before sealing for long-term storage. Keep away from heat and incompatible materials.
