(Methylene-d2)gibberellin A1 is an isotopic analog of Gibberellin A1 (G377495), 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. Molecular Formula: C19H22D2O6 Molecular Weight: 350.4
