Carbonate esters are a class of organic compounds formed by the reaction of carbonic acid with alcohols. They contain a carbonate group, which consists of a carbon atom bonded to three oxygen atoms, one of which is typically part of an alkyl or aryl group. These compounds are often used as solvents, plasticizers, and intermediates in chemical synthesis. In addition to their industrial applications, carbonate esters can also be found in nature and are studied for their potential use in pharmaceuticals. Their unique chemical structure allows for a variety of reactions, making them valuable in the development of new materials and chemicals.
