Quality Control

Our 2,4-Diethyl-1,3,2-Dioxaborolane is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and highly volatile nature, store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, and open flame.
