Chemische Eigenschaften
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).
Verwenden
Used to stimulate root formation of plant clippings. Suitable for plant cell culture tested.
Definition
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.
Allgemeine Beschreibung
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.
l?uterung methode
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.]
