rn: [100646-51-3]

Physical chemistry

Mol. wt.: 372.8; M.f.: C19H17ClN2O4; Form: White, crystalline, odourless solid. M.p.: 76.1-77.1 C. B.p.: 220 C/26.6 Pa V.p.: 1.1x10-4 mPa (20 C). KOW: logP = 4.66 S.g./density: 1.36 g/cm3 Solubility: In water 0.61 mg/l (20 C). In acetone, ethyl acetate and xylene >250, 1, 2-dichloroethane >1000 (all in g/l, 22-23 C); in methanol 34.87, n-heptane 7.168 (both in g/l, 20 C). Stability: Stable in neutral and acidic media, but unstable in alkaline media; DT50 <1 d (pH 9). Stable at high temperatures and in organic solvents. Specific rotation: [a]D20 +35.9?(20 C).


Biochemistry: Acetyl CoA carboxylase inhibitor; inhibition of fatty acid biosynthesis.

Mode of action: Systemic herbicide, absorbed from the leaf surface, with translocation throughout the plant, moving in both the xylem and phloem, and accumulating in the meristematic tissue.

Uses: Selective post-emergence control of annual and perennial grass weeds in potatoes, soya beans, sugar beet, peanuts, oilseed rape, sunflowers, vegetables, cotton, and flax.

Phytotoxicity: Most non-graminaceous crops are tolerant.

Formulation types: EC; SC.

Compatibility: Can be used in combination with post-emergence broad-leaved herbicides.

Mammalian toxicology

Oral: Acute oral LD50 for male rats 1210, female rats 1182, male mice 1753, female mice 1805 mg/kg.

NOEL: (90 d) for rats 7.7 mg/kg daily.

Toxicity class: EPA (formulation) II (5EC)


Birds: Acute oral LD50 for mallard ducks and bobwhite quail >2000 mg/kg.

Fish: LC50 (96 h) for rainbow trout >0.5 mg/l.

Daphnia: LC50 (48 h) 0.29 mg/l.

Algae: Assumed similar to racemate.

Bees: Assumed similar to racemate.

Worms: LC50 >1000 mg/kg.
