Quality Control

Our 2-(3-Decylthiophen-2-Yl)-4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity for research and development applications. Each lot undergoes comprehensive analytical characterization, including HPLC, NMR (1H, 13C, 11B), and GC-MS analysis. Certificates of Analysis (COA) with detailed specifications are provided to guarantee the material meets the stringent requirements of advanced synthetic chemistry.

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 (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition.
