Borate esters are chemical compounds formed by the reaction of boric acid with alcohols. They consist of boron atoms bonded to oxygen atoms, which are further connected to organic groups from the alcohols. These compounds are often used in various applications, including as preservatives, flame retardants, and in the production of glass and ceramics. In addition to their industrial uses, borate esters can also play a role in biological systems. They have been studied for their potential benefits in agriculture, particularly as fertilizers and pest control agents. Their unique properties make them valuable in both commercial and scientific fields.
