Quality Control

Our 4-(Naphthalene-1-Yl)Phenylboronic 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 structural integrity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, identity, and impurity profiles to support your quality assurance and regulatory documentation 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). The compound is moisture-sensitive; keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent hydrolysis of the boronic ester group.
