Indole-3-butyric acid (IBA) is a white to light yellow powder or crystalline solid with a slight characteristic odor. It is practically insoluble in chloroform, but is soluble in alcohol, ether and acetone. The solubility of IBA in water is 250 mg L-1 (EPA, 2010).
용도
Used to stimulate root formation of plant clippings. Suitable for plant cell culture tested.
정의
ChEBI: Indole-3-butyric acid is a indol-3-yl carboxylic acid that is butanoic acid carrying a 1H-indol-3-yl substituent at position 1. It has a role as a plant hormone, a plant metabolite and an auxin. It derives from a butyric acid. It is a conjugate acid of an indole-3-butyrate.
일반 설명
Indole-3-butyric acid is a plant hormone in the auxin family and is widely used in agriculture since it induces rooting in various plants species such as mung bean (Vigna radiata?L.) cuttings.
Purification Methods
Recrystallise the acid from H2O. It is soluble in EtOH, Et2O and Me2CO but insoluble in CHCl3. [Bowman & Islip Chem Ind London 154 1971, Jackson & Manske J Am Chem Soc 52 5029 1930, Albaum & Kaiser Am J Bot 24 420 1937.] It has also been recrystallised from EtOH/water [James & Ware J Phys Chem 89 5450 1985]. Its UV has 278 and 320nm in isoPrOH [Elvidge Quart J Pharm Pharmacol 13 219 1940].max The methyl ester has m 73-74o (from *C6H6/pet ether) and b 230o/6mm [Bullock & Hand J Am Chem Soc 78 5854 1951]. [Beilstein 22 III/IV 1128, 22/3 V 140.]
