Isocyanic Acid – Reactive Intermediate

Wholesale Supplier of  Isocyanic Acid, chemically represented as HNCO, is the simplest isocyanate and a volatile, colorless compound with a sharp, acrid odor. As a monobasic acid, it is characterized by the functional group -N=C=O, which enables it to readily react with water, alcohols, and amines, forming ureas, carbamates, and isocyanates. It plays a critical role as a reactive intermediate in various organic and polymer synthesis pathways.

HNCO can be produced industrially through thermal decomposition of urea or oxidation of ammonia and is typically handled in gas form or in stabilized solutions due to its instability at room temperature. It’s widely used in the production of polyurethanes, agrochemicals, coatings, 和 elastomers.

卡文资源 supplies 异氰酸 to industrial buyers and research labs worldwide with safety data sheets (SDS), technical specifications, and custom packaging solutions for safe handling and regulatory compliance.
