Quality Control

Our N,N'-[Methylenebis(4,1-Phenylene)]Bis[Chloroformamide] is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
