Quality Control

Our Diethyl(3,4-Dihydronaphthalen-1-Yloxy)Borane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for research and process development. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to cGMP guidelines where applicable to support our clients in regulated development pathways.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) to prevent degradation from moisture. Keep away from heat, sparks, and open flame.
