DL-Mandelic acid Chemical Properties,Usage,Production

Chemical Properties

White rhomboidal crystals, decompose when exposed to light. Soluble in ether and isopropanol, soluble in ethanol and water; R-form melting point is 133°C, [α]-159.73° (ethanol), gradually racemic at 160°C. S-form melting point is 133.8°C, [α]+156.57° (water).

Uses

Organic synthesis, medicine (urinary antiseptic).

Uses

DL-Mandelic acid may be used as an analytical reference standard for the determination of DL-mandelic acid in:
Human urine samples by high performance liquid chromatography (HPLC) equipped with ultraviolet (UV) detector.
Rat urine samples by gas chromatography-mass spectrometry (GC-MS) with selected ion monitoring (SIM) detection.

Preparation

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

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 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.

General Description

DL-Mandelic acid is an aromatic hydrocarbon metabolite of styrene.

Hazard

Toxic by ingestion.

Flammability and Explosibility

Not classified

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.
