Quality Control

Our Ethyldimethoxyboron is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including NMR, GC, and titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing specific results are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition.
