Quality Control

Our Borane, Dichloro(2-Methylcyclopentyl)-, (1S-Trans)- (9Ci) is produced under stringent conditions to ensure high chiral purity and chemical integrity. Each batch undergoes comprehensive analytical testing, including chiral HPLC, NMR, and titration methods, to confirm identity, purity, and enantiomeric excess. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality parameters.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile, hygroscopic (moisture-sensitive), and easily oxidized nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, strong bases, and oxidizing agents.
