Quality Control

Our high-purity boronic ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR (¹H and ¹³C), and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications 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 place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (argon or nitrogen) to prevent hydrolysis and maintain stability. Keep away from heat and incompatible materials.
