A type of chemical compound that includes both a cyanide group and a hydroxyl group.
Cyanohydrins are important in organic chemistry for synthesizing other compounds.
Cyanohydrin is formed from "cyano-" (from Greek "kyanos", meaning dark blue or cyan) and "hydrin" (from the Greek "hydor", meaning water). The term refers to a compound containing a cyanide group and a hydroxyl group, thus relating to both cyanide and water.
Think of 'cyan' as relating to the color blue and 'hydrin' as relating to water, which helps you remember that cyanohydrin is a compound involving both cyanide and water.
