Quality Control

Every batch of our 2-(3,3-Dimethylbut-1-En-2-Yl)-4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane undergoes rigorous analytical testing to ensure it meets the high-purity standards required for sensitive synthetic applications. Our quality assurance protocols include NMR, HPLC, and GC analysis to verify identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing all relevant specifications. We adhere to strict GMP and ISO 9001 principles in our manufacturing and quality control processes to guarantee batch-to-batch consistency and reliability.

Storage

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