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 stereochemical integrity. Certificates of Analysis (COA) detailing specifications such as chiral purity (enantiomeric excess), chemical purity (by GC/HPLC), and residual solvent content are available upon request. We adhere to cGMP principles where applicable to support our clients' regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be amber-colored or stored in dark conditions.
