Aromatic isocyanates are organic compounds characterized by the presence of an isocyanate group (-N=C=O) attached to an aromatic ring. They are commonly used in the production of polyurethanes, which are versatile materials found in foams, coatings, and adhesives. Due to their reactivity, these compounds play a crucial role in various industrial applications. These isocyanates can be hazardous, as they may cause respiratory issues and skin irritation upon exposure. Safety measures, such as proper ventilation and protective equipment, are essential when handling aromatic isocyanates. Common examples include toluene diisocyanate (TDI) and methylenediphenyl diisocyanate (MDI).
