3-Indolepropionic acid Chemical Properties,Uses,Production

Chemical Properties

pale yellow to yellow crystalline powder


ChEBI: An indol-3-yl carboxylic acid that is propionic acid substituted by a 1H-indol-3-yl group at position 3.

Purification Methods

Recrystallise it from EtOH/water [James & Ware J Phys Chem 89 5450 1985]. The picrate has m 143-144o, and the methyl ester crystallises from *C6H6 or MeOH with m 81-83o. [Beilstein 22 III/IV 1113, 22/3 V 114.]
