Indole-3-butyric acid (1H-Indole-3-butanoic acid, IBA) is a white to light-yellow crystalline solid, with the molecular formula C₁₂H₁₃NO₂. It melts at 125 °C in atmospheric pressure and decomposes before boiling.

Plant hormone

IBA is a plant hormone in the auxin family and is an ingredient in many commercial horticultural plant rooting products.

Since IBA is not soluble in water, it is typically dissolved in 75% or purer alcohol for use in plant rooting, making a solution of between 10,000 to 50,000 ppm. This alcohol solution is then diluted with distilled water to the desired concentration. IBA is also available as a salt, which is soluble in water. The solution should be kept in a cool, dark place for best results.

This compound had been thought to be strictly synthetic; however, it was reported that the compound was isolated from leaves and seeds of maize and other species. This chemical may also be extracted from any of the Salix (Willow) genus.
