|Stability||Solubility in water 1.4mg/L, 45, in acetone 48.2 g/L, 105g/l in methanol; slightly soluble in toluene about 5g/l, 17 g/l in isopropanol , 0.9 g/l in heptanc,very slightly soluble in heptane.|
|Application||It is an imidazole compound used as a selective herbicide. It is applied preplant incorporated, preemergence, at cracking, and postemergence. The compound controls weeds by reducing the levels of three branched-chain aliphatic amino acids, isoleucine, leucine and valine, through the inhibition of aceto-hydroxyacid synthase, an enzyme common to the biosynthetic pathway for these amino acids.|
