m-phenylene diisocyanate

Description:
m-Phenylene diisocyanate (CAS 123-61-5) is an organic compound characterized by the presence of two isocyanate functional groups attached to a benzene ring at the meta positions. This colorless to pale yellow liquid is known for its high reactivity, particularly with nucleophiles such as amines and alcohols, making it valuable in the production of polyurethanes and other polymers. It has a relatively high boiling point and is soluble in organic solvents, but it is insoluble in water. m-Phenylene diisocyanate is also recognized for its potential health hazards; it can cause respiratory irritation and sensitization upon exposure, necessitating the use of appropriate safety measures during handling. Additionally, it is classified as a hazardous substance, and its use is regulated in many jurisdictions due to its toxicological properties. Overall, m-phenylene diisocyanate is an important intermediate in the chemical industry, particularly in the manufacture of coatings, adhesives, and elastomers.
