CAS 101-68-8: Benzene, 1,1'-methylenebis[4-isocyanato-

Description: The chemical substance known as Benzene, 1,1'-methylenebis[4-isocyanato-], commonly referred to as MDI (Methylene Diphenyl Diisocyanate), is an aromatic isocyanate used primarily in the production of polyurethane foams and coatings. It is characterized by its high reactivity due to the presence of isocyanate functional groups, which readily react with compounds containing active hydrogen atoms, such as alcohols and amines. MDI is typically a viscous liquid or solid at room temperature, with a distinct aromatic odor. It is insoluble in water but soluble in organic solvents like acetone and toluene. MDI is known for its excellent thermal stability and mechanical properties, making it suitable for various industrial applications, including insulation materials and elastomers. However, it is also associated with health risks, as exposure can lead to respiratory issues and skin sensitization, necessitating proper handling and safety precautions in industrial settings.
