Quality Control

Our 2-Ethyl-4,5-Dimethyl-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. Certificates of Analysis (COA) are provided with each shipment, detailing all relevant specifications. We adhere to cGMP principles where applicable to support our clients in regulated industries.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong acids and incompatible organic solvents.
