Lactonitrile is theorganic compound with the formula CH3CH(OH)CN. It is an intermediate in the industrial production ofethyl lactate andlactic acid.[1][2][3] It is thecyanohydrin ofacetaldehyde. It is a colorless liquid, although degraded samples can appear yellow.
Lactonitrile is obtained by the addition ofhydrogen cyanide toacetaldehyde.[1]
Lactonitrile is used in making esters of lactic acid.[1]
Cyanohydrins are sources of highly toxichydrogen cyanide.The substance is classified as anextremely hazardous substance in the United States as defined in Section 302 of the U.S.Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.[4]
