Quality Control

Our Propane-1,2,3-Triyl Tris[(3-Isocyanatomethylphenyl)Carbamate] is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including assay, isocyanate content determination, and impurity profiling, to ensure it meets precise specifications for high-performance applications. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, this material must be stored under a dry, inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C to maintain stability and prevent premature polymerization. Keep away from heat, sparks, open flames, and sources of moisture.
