1,4-Diisocyanobenzene

Description:
1,4-Diisocyanobenzene, also known as p-phenylenediisocyanide, is an organic compound characterized by the presence of two isocyanate (-N=C=O) functional groups attached to a benzene ring at the para positions. Its molecular formula is C8H6N2O2, and it has a molecular weight that reflects its structure. This compound is typically a solid at room temperature and is known for its high reactivity, particularly in forming polyurethanes and other polymers through reactions with alcohols and amines. 1,4-Diisocyanobenzene is also used in the synthesis of various chemical intermediates and materials. Due to the presence of isocyanate groups, it can be hazardous, posing risks such as respiratory irritation and sensitization upon exposure. Proper handling and safety precautions are essential when working with this compound. Additionally, it is important to note that 1,4-Diisocyanobenzene should be stored in a cool, dry place, away from moisture and incompatible substances to maintain its stability and prevent degradation.
