Quality Control

Our Bisphenol Z Bis(Chloroformate) 97 is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. The product undergoes rigorous analytical testing, including chromatography and spectroscopy, to verify identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each 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, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong acids, bases, and sources of ignition.
