CAS 104-49-4
:p-Phenylene diisocyanate
Description:
p-Phenylene diisocyanate (CAS 104-49-4) is an organic compound characterized by its two isocyanate functional groups attached to a phenylene ring. It appears as a colorless to pale yellow liquid and is known for its strong reactivity, particularly with nucleophiles, due to the presence of the isocyanate groups. This compound is primarily used in the production of polyurethane elastomers, coatings, and adhesives, where it contributes to the formation of cross-linked structures that enhance material durability and flexibility. p-Phenylene diisocyanate is also recognized for its potential health hazards; it can be an irritant to the skin, eyes, and respiratory system, and prolonged exposure may lead to sensitization or other adverse effects. Therefore, handling this substance requires appropriate safety measures, including the use of personal protective equipment and adequate ventilation. Its reactivity and toxicity necessitate careful management in industrial and laboratory settings.
