Quality Control

Our 2-Ethyl-4,5-Dimethyl-6-Phenyl-1,3,2-Dioxaborinane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, NMR, and GC analysis, to confirm identity, potency, and impurity profiles. Certificates of Analysis (COA) detailing all specifications and test results are provided with every shipment to support your quality assurance and regulatory compliance 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.
