Physical Properties

Molecular weight:266.4g/mol. amber liquid, with a waxy odour. Boiling point:174℃/19 mmHg; 138-140℃/1.25 mmHg; ((S)-hydroprene >262 ℃) Vapour pressure: 40 mPa (25℃, gas saturation method) KOW logP = 3.06 S.g./density 0.892 (25℃); ((S)-hydroprene 0.889 (20℃)) Solubility In water 2 mg/l (pH 7, 25℃); ((S)-hydroprene c. 5.05 mg/l). Soluble in common organic solvents. Stability Stable for more than 3 years under normal storage conditions. Sensitive to u.v. light.

Toxicology

Oral Acute oral LD50 for rats >5000, dogs >10 000 mg/kg.Skin and eye Acute percutaneous LD50 for rats >5000, rabbits >5100 mg/kg. Non-irritating to skin; mild eye irritant (rabbits).Inhalation LC50 (4 h) for rats >5.5 mg/l air.

Environmental Profile

Ecotoxicology:

Algae:EC₅₀ (24-72 h) for Scenedesmus subspicatus 6.35 mg/ml.Bees: LD₅₀ for adult bees (oral and contact) >1000mg/bee. Bee larvae affected at 0.1 mg/bee.Daphnia:EC₅₀(48 h) 0.13 mg/l.Fish: LC₅₀ (96 h) for rainbow trout >0.50 mg/l.

Environmental fate:
Soil:In soil, rapidly decomposed, DT₅₀ is only a few days.Plant:In plants, degradation principally involves ester hydrolysis, O-demethylation, and oxidative splitting of the double bond.

Transport Information

Hazard Class:III(Slightly hazardous)
