Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized using advanced analytical techniques to confirm identity, purity, and chiral integrity. Certificates of Analysis (COA) detailing specific results for chiral purity (enantiomeric excess), assay, and impurity profiles are available upon request. We adhere to cGMP principles for the production of high-purity research chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This compound 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. Keep away from heat, sparks, and open flame.
