Quality Control

Every batch of our chiral intermediates is produced and tested under a strict quality management system. We provide comprehensive Certificates of Analysis (COA) detailing purity, enantiomeric/excess, and impurity profiles, typically determined by advanced chromatographic methods (HPLC, GC). Our commitment ensures the reproducible quality and stereochemical integrity required for critical R&D and scale-up processes.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) to prevent oxidation and maintain stability. Keep the container in a cool, dry, and well-ventilated area.
