3-Chloro-4-methylphenylisocyanate Chemical Properties, Uses, Production

Chemical Properties

Chloromethyl phenyl isocyanate is a colorless to yellow liquid or beige, low-melting solid. Acrid odor.

Uses

It is employed as a intermediates for pharmaceutical.

Potential Exposure

This material is used in organic synthesis.

Shipping

UN22363-Chloro-4-methylphenyl isocyanate, liquid, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Incompatibilities

May form explosive mixture with air. Isocyanates are highly flammable and reactive with many compounds, even with themselves. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Reaction with moist air, water or alcohols may form amines and insoluble polyureas and react exothermically, releasing toxic, corrosive, or flammable gases, including carbon dioxide; and, at the same time, may generate a violent release of heat increasing the concentration of fumes in the air. Incompatible with amines, aldehydes, alkali metals, ammonia, carboxylic acids, caprolactum, alkaline materials, glycols, ketones, mercaptans, hydrides, organotin catalysts, phenols, strong acids, strong bases, strong reducing agents such as hydrides, urethanes, ureas. Elevated temperatures or contact with acids, bases, tertiary amines, and acyl-chlorides may cause explosive polymerization. Attacks some plastics, rubber, and coatings. Contact with metals may evolve flammable hydrogen gas. May accumulate static electrical charges, and may cause ignition of its vapors. Do not store in temperatures above 30C/86F.
