Quality Control

Every batch of our chiral intermediates is produced and tested under strict quality management protocols to ensure identity, purity, and enantiomeric excess. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, chiral purity (by chiral HPLC or GC), and impurity profiles. Our quality systems support development from milligram to kilogram scale with consistent traceability and documentation.

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). Due to its highly volatile nature, ensure containers are securely sealed and stored upright. Keep away from heat, sparks, and open flame.
