Quality Control

Our 4-[4-(Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl]Phenyl Acetate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and identity confirmation. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, assay, and impurity profiles 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 a controlled 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.
