Quality Control

Every batch of our chiral intermediates is produced and controlled under a strict quality management system. We provide comprehensive analytical data to ensure identity, purity, and enantiomeric excess meet the exacting standards required for research and development. Certificates of Analysis (COA) detailing specifications such as assay (by GC/HPLC), chiral purity (by Chiral HPLC), and impurity profile are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its highly volatile nature, ensure containers are properly sealed when not in use and stored away from heat and ignition sources.
