DescriptionIndoleacetic acid, also known as indoleacetate or IAA, belongs to the class of organic compounds known as indole-3-acetic acid derivatives. Indole-3-acetic acid derivatives are compounds containing an acetic acid (or a derivative) linked to the C3 carbon atom of an indole. Indoleacetic acid is a weakly acidic compound (based on its pKa). Indoleacetic acid is a potentially toxic compound.
