Physical Properties
Molecular weight:185.4; Physical form:Yellowish, deliquescent powder. Composition:The name TCA has been used variously to refer either to the acid or to the sodium salt (see Common name). The names used here are trichloroacetic acid (for the acid) and TCA-sodium (for the salt). Melting point:Decomposes at 165-200 °C; Vapour pressure:<0.1 mPa (70 °C); Solubility:In water 1.2 kg/l (25 °C). In methanol 232, acetone 7.6, diethyl ether 0.2, benzene 0.07, carbon tetrachloride 0.04, heptane 0.02 (all in g/l, 25 °C).; Stability:Stable under dry conditions, but decomposes in aqueous, strongly alkaline media.;
Toxicology
Oral:Acute oral LD50 for rats 3200-5000, mice 3600-5600 mg/kg. Percutaneous:Acute percutaneous LD50 for rats >2000 mg/kg. Irritant to skin, eyes, and mucous membranes. Corrosive to skin on prolonged contact. Inhalation: LC50 (4 h) for rats >365 mg/l air.
Environmental Profile
Ecotoxicology: 
Bees:Not toxic to bees.Birds:Acute oral LD50 for chickens 4280 mg/kg.Fish:Not toxic to fish. Threshold value for toxic activity c. 11 000 mg/l for perch. 

Environmental fate: 
Soil:In soil, microbial degradation involves chloride formation, but is slower than for dalapon-sodium. TCA-sodium is not tightly adsorbed, and may be leached by heavy rainfall. Persists in soil for c. 21-90 days, depending upon rate applied, soil moi
Transport Information
Signal Word:CAUTION; Hazard Class:III(Slightly hazardous)
