Infobox disclaimer and references

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 auxin family and is an ingredient in many commercial plant rooting horticultural products.

For use as such, it should be 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.[1]
