4-Iodo 3-Dehydro Gibberellic Acid is an intermediate in the synthesis of Gibberellin A72 (G377505), a derivative of Gibberellic Acid (G377450), a hormone that is found in plants which promotes the growth and elongation of cells. Gibberellic acid acts as a plant growth regulator on account of its physiological and morphological effects in extremely low concentrations.
