Quality Control

Our 4-Bromo-2,6-Dimethylphenylboronic Acid Pinacol Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, assay, 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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for prolonged storage or after opening to maintain stability and purity.
