Roth: (S)-3-allyl-2-methyl-4-oxocyclopent-2-enyl (1R)-trans-2, 2-dimethyl-3-(2-methylprop-1-enyl)cyclopropanecarboxylate

Chemical Abstracts name: [1R-[1a(S*), 3a]]-2-methyl-4-oxo-3-(2-propenyl)-2-cyclopenten-1-yl 2, 2-dimethyl-3-(2-methyl-1-propenyl)cyclopropanecarboxylate

Other names: Esbiol; S-biothrin; esdepalléthrine

Cas rn: [28434-00-6]

EEC no.: 249-013-5

Physical chemistry

Composition: Esbiol contains 95% m/m total isomers, of which 90% is esdepalléthrine. the remainder being essentially the (R)-cyclopentenyl isomer, with <3% cis- isomers. Mol. wt.: 302.4; M.f.: C19H26O3; Form: Orange-yellow viscous liquid. M.p.: Not applicable; no crystallisation observed at -40 ºC. B.p.: 165-170 ºC/0.15 mmHg (OMS 3046); 163-170 ºC/0.15 mmHg (OMS 3045). V.p.: 44 mPa (25 ºC). S.g./density: 1.010 at 20 ºC. Solubility: Completely miscible with 100% ethanol, acetone, dichloromethane, di-isopropyl ether, toluene, n-hexane, chloroform, ethyl acetate, methanol, n-octanol, and petroleum solvent (20 ºC). Stability: Degraded by u.v. light. F.p.: 113 ºC (open cup).


Mode of action: Non-residual insecticide with rapid knockdown action.

Uses: Esbiol is by far the most potent constituent of allethrin. OMS 3046 is used in aerosols, coils, electric vapourisers, or sprays indoors against flying and crawling insects (Blattodea, Culicidae, Muscidae). Also used in aerosols and sprays in mixtures with other pyrethroids and piperonyl butoxide. OMS 3045 has similar uses to OMS 3046.

Formulation types: AE; OL; UL; VP; Water-miscible liquid.

Skin and eye: Acute percutaneous LD50 for rabbits:- 1545 mg Esbiol/kg, >2000 mg OMS 3045/kg, >2000 mg OMS 3046/kg.

Inhalation: LC50 (4 h) for rats c. 1.26 mg Esbiol/l air, c. 2.63 mg OMS 3045/l air.
