Indole-3-acetic acid Chemical Properties,Uses,Production

Chemical Properties

white to tan crystals

Definition

ChEBI: A monocarboxylic acid that is acetic acid in which one of the methyl hydrogens has been replaced by a 1H-indol-3-yl group.

Uses

Plant growth regulator.

Purification Methods

Recrystallise heteroauxin from EtOH/water [James & Ware J Phys Chem 89 5450 1985]. [Beilstein 22 III/IV 65.] Alternatively recrystallise 30g of the acid with 10g of charcoal in 1L of hot water, filter and cool when 22g of colourless acid separate. Dry it and store it in a dark bottle away from direct sunlight [Johnson & Jacoby Org Synth Coll Vol V 654 1973]. The picrate has m 178-180o. [Beilstein 22 H 66, 22 I 508, 22 II 50, 22 III/IV 1088.] It is a plant growth substance.
