Quality Control

Our 3,4-(Methylenedioxy)Phenyl Isocyanate is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the specific requirements of our global B2B clients. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each 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 (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
