M.F.: C17H26ClNO2 Mol Wt: 311.9 Form (appearance): Colourless liquid. B.P.: 135/0.001 mmHg V.P.: 0.133 mPa (20) F.P.: 129 (EEC A.9) S.G.: 1.076 (20) Solubility.: In water 50 mg/l (20). Very soluble in benzene, hexane, methanol and dichloromethane. Stability: Relatively stable to hydrolysis; DT50 (catc.) (20) >200 d (pH 1-9), 14 d (pH 13). Henry: 8.1 × 10-4 Pa m3 mol-1 KowlogP: 4.08 (shake flask) Biochemistry: Cell division inhibitor. Mode of action: Selective herbicide. It is taken up readily by the hypocotyls, mesocotyls and coleoptites, and, to a lesser extent, by the roots of germinating weeds.
