Quality Control

Our 2-(2-Cyclopropylprop-1-En-1-Yl)-4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane is manufactured under strict quality systems to ensure batch-to-batch consistency and high purity for sensitive applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles as verified by NMR, HPLC, and GC analysis. We adhere to cGMP principles where applicable to support our clients in regulated research and development.

Storage

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