Physical Properties
Molecular weight:144.5; Physical form:Colourless solid; ( tech. is a clear liquid). Density:1.409.02 (20 °C) ( tech.); Melting point:74-75 °C; Vapour pressure:<0.01 mPa (20 °C); Henry constant:<1.55 × 10-9 Pa m3 mol-1 ( calc.); Partition coefficient(n-octanol and water):logP <-2.20 (25 °C, unstated pH); pKa: pKa1 2.5, pKa2 7.2; Solubility:In water c. 1 kg/l (23 °C). Readily soluble in methanol, ethanol, isopropanol, acetone, diethyl ether, and other polar organic solvents. Sparingly soluble in non-polar organic solvents such as benzene and toluene. Insoluble in ke; Stability:Stable in aqueous solutions having pH <5. At higher pH, decomposition occurs with the liberation of ethylene. Sensitive to u.v. irradiation.;

Oral:Acute oral LD50 for rats 3030 mg/ kg ( tech.). Percutaneous:Acute percutaneous LD50 for rabbits 1560 mg/ kg ( tech.). Irritating to skin and eyes. Inhalation: LC50 (4 h) for rats 6.26 mg/l ( tech.).
Environmental Profile
Ecotoxicology: 
Algae: EC50 (24-48 h) for Chlorella vulgaris 32 mg/l.Bees:Not toxic to bees.Birds:Acute oral LD50 for bobwhite quail 1072 mg/50 (8 d) for bobwhite quail >7000 ppm in diet (tech.50 (48 h) 577.4 mg/l.Fish: LC50(96 h) for carp >140, rainbow trout 720 mg/l ( tech.).Worms:Not toxic to earthworms.Other aquatic spp.:Low toxicity. 

Environmental fate:
Animals:In animals, ethephon is rapidly excreted intact via the urine, and as ethylene via the expired air.Soil:Rapidly degraded in soil, and strongly adsorbed; unlikely to leach.Plant:In plants, ethephon rapidly undergoes degradation to ethylene."
Transport Information
Signal Word:DANGER; Hazard Class:Ib(Highly hazardous)
