DL-Mandelic acid Usage And Synthesis
Chemical Properties
Mandelic acid turns brown when exposed to light. It can be esterified easily with alcohols in the presence of hydrogen chloride.
Physical properties
(R,S)-Mandelic acid (a-hydroxyphenylacetic acid, phenylglycolic acid), C6H5CH(OH)COOH, C8H8O3, Mr 152.15, mp 118 – 121℃, is a colorless crystalline powder. It is readily soluble in ethanol and diethyl ether, less soluble in chloroform, and insoluble in petroleum ether. Its water solubility is 15 g per 100 mL of water. In alkaline solution, mandelic acid dissolves to form salts.
Definition
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 is functionally related to an acetic acid. It is a conjugate acid of a mandelate.
Production Methods
(R,S)-mandelic acid is produced by hydrolysis of mandelic acid nitrile [532-28-5] (mp 10℃) with hydrochloric acid. Mandelic acid nitrile is obtained by the conversion of benzaldehyde [100-52-7] and hydrogen cyanide in the nascent state (NaCN + HCl) under refrigeration. Another method of producing mandelic acid is the hydrolysis of a,a-dichloroacetophenone with alkali.
