Quality Control

Our 2-(4-Cyclopropylphenyl)-4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including NMR (1H, 13C, 11B), HPLC, and GC analysis, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, confirming compliance with customer specifications and industry standards for fine chemical intermediates.

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 (moisture-sensitive) nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
