【 Indole-3-acetic acid CAS 87-51-4 】

Product:Indole-3-acetic acid


Chemical properties:White crystalline powder, Melting point 165-166 ℃ (168-170 ℃). Easily soluble in acetone and ether, slightly soluble in chloroform, insoluble in water.

Used as a plant growth stimulating hormone and analytical reagent. 3-Indoleacetic acid, as well as 3-indolealdehyde, 3-indoleacetonitrile, ascorbic acid and other auxin like substances, are naturally present in nature. The precursor of 3-indoleacetic acid biosynthesis in plants is tryptophan. The basic function of auxin is to regulate plant growth. Not only promotes growth, but also has inhibitory effects on growth and organogenesis. In plant cells, auxin exists not only in a free state, but also in bound auxin forms that firmly bind to biopolymers, as well as in auxin forms complexes with special substances such as indole acetyl asparagine, indole acetic acid pentose, and indole acetylglucose. This may be a storage method for auxin in cells and a detoxification method for detoxifying excess auxin.
