Quality Control

Our production of Carbonic Dichloride, Polymer With 4,4-(1-Methylethylidene)Bisphenol adheres to rigorous quality protocols to ensure batch-to-batch consistency and performance. Quality is verified through analytical methods including GPC (Gel Permeation Chromatography) for molecular weight distribution, FT-IR for structural identification, and titration for chloroformate content. A comprehensive Certificate of Analysis (COA) detailing purity, residual solvents, and other critical parameters is provided with each 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 area. Due to the reactive chloroformate groups, this material is moisture-sensitive (hygroscopic) and should be handled under a dry inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent hydrolysis. Recommended storage temperature is 2-8°C for extended stability. Keep away from strong bases, amines, alcohols, and moisture.
