Quality Control

Our 1,3,2-Dioxaborolane, 2-(9,9-Dimethyl-9H-Fluoren-2-Yl)-4,4,5,5-Tetramethyl is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC analysis, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

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 must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
