Quality Control

Our 3,4-Dichlorophenylboronic Acid, Pinacol Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee consistency and reliability for your critical synthetic applications.

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); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent decomposition.
