Chemical properties
WHITE CRYSTALS
Definition
ChEBI: Atrolactic acid is a 2-hydroxy monocarboxylic acid.
Purification Methods
Crystallise the acid from water (4g/20ml boiling H2O with charcoal, filter and cool overnight at 0-5o) and dry it at 55o/0.5mm [Eliel & Freeman Org Synth Coll Vol IV 58 1963]. The (±)-ethyl ester [76496-51-0] has b 250o/~760mm, 129 -130o/13mm, and the (±)-amide [5908-94-1] has m 101-102o. [Beilstein 10 H 259, 10 I 113, 10 II 157, 10 III 560, 10 IV 467.]
