정의
ChEBI: Mandelic acid is a 2-hydroxy monocarboxylic acid that is acetic acid in which two of the methyl hydrogens are substituted by phenyl and hydroxyl groups. It has a role as an antibacterial agent and a human xenobiotic metabolite. It is a 2-hydroxy monocarboxylic acid and a member of benzenes. It derives from an acetic acid. It is a conjugate acid of a mandelate. Exists in stereoisomeric forms. The properties are those of the dl-form.제조 방법
Mandelic acid can be prepared by the hydrolysis of amygdalin with sulfuric acid or of mandelonitrile with hydrochloric acid. The mandelonitrile can be prepared by the action of hydrocyanic acid on benzaldehyde, and by the action of sodium or potassium cyanide on the sodium bisulfite addition product of benzaldehyde. The procedure described differs from earlier methods in that the sodium bisulfite addition compound of benzaldehyde is prepared in the presence of sodium cyanide and the nitrile is formed immediately.synthesis of mandelic acid
일반 설명
DL-Mandelic acid is an aromatic hydrocarbon metabolite of styrene.위험도
Toxic by ingestion.Safety Profile
Poison by intramuscular route. Moderately toxic by ingestion. Continued absorption can cause kidney irritation. When heated to decomposition it emits acrid smoke and irritating fumes.만데릭산 준비 용품 및 원자재
