Quality Control

Our production of 4,4,5,5-Tetramethyl-2-(Phenanthren-9-Yl)-1,3,2-Dioxaborolane adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for sensitive applications. Each lot undergoes comprehensive analytical characterization, including NMR, HPLC, and elemental analysis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is 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.
