CAS 5124-30-1

4,4'-methylenebis(cyclohexyl isocyanate)

Description:

4,4'-Methylenebis(cyclohexyl isocyanate), with the CAS number 5124-30-1, is an organic compound characterized by the presence of two isocyanate functional groups attached to cyclohexyl rings, linked by a methylene bridge. This compound is typically a colorless to pale yellow liquid at room temperature and is known for its reactivity, particularly in forming polyurethanes through polymerization reactions with polyols. It exhibits a relatively high viscosity and has a distinct, pungent odor. As an isocyanate, it is classified as a hazardous material, requiring careful handling due to its potential to cause respiratory irritation and skin sensitization. The compound is primarily used in the production of coatings, adhesives, and elastomers, where its ability to cross-link with other materials enhances durability and mechanical properties. Proper safety measures, including the use of personal protective equipment and adequate ventilation, are essential when working with this substance to mitigate health risks associated with exposure.
