APPLICATIONS
Cyanohydrins are organic compounds which contain both cyano and hydroxyl groups linked to the same carbon atom usually. Cyanothydrins are obtained from the reactions of aldehydes (or ketones) with hydrogen cyanide in base. They are versatile intermediates for the synthesis of organic compounds including amino nitriles; alpha-hydroxy acids, esters and amides; alpha-, beta-unsaturated acids, esters, nitriles as well as beta-aminoalcohols. Acetone Cyanohydrin is used to manufacture insecticides, pharmaceuticals and flavouring agents. It is an important intermediate to prepare methacrylic acid and methacrylates.
