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.

As a Plant Hormone

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

For use as such, it should be dissolved in about 75% (or purer) alcohol (as IBA does not dissolve in water), until a concentration from between 10,000 ppm to 50,000 ppm is achieved - this solution should then be diluted to the required concentration using distilled 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 compounds was isolated from leaves and seeds of maize and other species.William. G.Hopkins(1999). Introduction to Plant Physiology. John Wiley and Sons. ISBN 0-471-19281-3
