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.

HMDI, mixture of isomer

CAS: 5124-30-1

Hydroxyl-terminated polydimethylsiloxane (HMDI) is a glycol ether that is used as a polymerization catalyst. It has been shown to be chemically stable and does not react with biological molecules, such as antibodies or cells. HMDI can also be used for the synthesis of polyurethanes and fatty acids. The reaction mechanism of HMDI involves the formation of a hydroxyl group from two molecules of water, which is then hydrogenated to form hydrogen fluoride. This product can be made by reacting diisocyanates with an alcohol and a fatty acid.
