Quality Control

Every batch of our chiral intermediates is produced under strict quality management systems. We provide comprehensive analytical data to ensure high chemical and enantiomeric purity, critical for sensitive synthetic applications. Certificates of Analysis (COA) detailing identity (IR, NMR), assay (HPLC/GC), chiral purity (Chiral HPLC), and impurity profiles are supplied with each shipment. Our commitment to consistent quality and traceability supports your R&D and scale-up processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its properties as a highly volatile and easily oxidized compound, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation of quality. Keep away from heat, sparks, and open flame.
