위험도

Toxic by ingestion and inhalation, a possible carcinogen.

건강위험

The toxicity of this compound is moderatein rats; an oral lethal dose is 200 mg/kg.Oral administration of thioacetamide causedliver cancer in rats and mice. It is, however, a weak liver carcinogen. Malvaldi and associates (1988) investigated the mechanism of its carcinogenic activity on rat liver.Whereas the initiating ability of this compound is quite low, its promoting effect isstrong. Thus thioacetamide is a very effectivepromoter of the liver carcinogenesis. A similar promoting activity of liver carcinogenesishas been observed with other thioamide substances, such as thiobenzamide (Malvaldi et al. 1986).
Low et al. (2004) have proposed a modelto explain thioacetamide-induced hepatotoxicity and cirrhosis in rat livers. The pathways of thioacetamide-induced liver fibrosiswere found to be initiated by thioacetamideS-oxide derived from the biotransformationof thioacetamide by the microsomal flavinadenine nucleotide containing monooxygenase and cytochrome P450 systems andinvolve oxidative stress and depletion ofsuccinyl-CoA, thus affecting heme and ironmetabolism. Karabay et al. (2005) observedsuch hepatic damage in rats with elevationof total nitrite level in livers and decrease inarginase activity. The authors have reportedthat nitrosative stress was essentially the critical factor in thioacetamide-induced hepaticfailure in rats.
Pretreatment of rats with jigrine exhibited hepatoprotective action againstthioacetamide-induced toxicity (Ahmed et al.1999). Thioacetamide decreased the concentration of glutathione in the liver of rats.Jigrine pretreatment, however, restored theglutathione levels to the near normal values.The authors claimed that the effects of jigrinewere comparable to that of silymarin. Thehepatotoxicity in rats was found to potentiatefollowing pretreatment with phenobarbital.
Al-Bader et al. (2000) investigated thetoxicity of thioacetamide in the spleen inexperimental animals. The authors foundan intimate association between the levelsof trace metals and spleen pathology, asobserved in studies of other organs.

화재위험

Flash point data on Thioacetamide are not available; Thioacetamide is probably combustible.

Safety Profile

Confirmed carcinogen with experimental carcinogenic, neoplas tigenic, tumorigenic, and teratogenic data. Poison by ingestion and intraperitoneal routes. Moderately toxic by subcutaneous route. Human mutation data reported. An experimental teratogen. Experimental reproductive effects. Exposure has caused liver damage. When heated to decomposition it emits very toxic fumes of NOx and SOx. See also SULFIDES and MERCAPTANS.

잠재적 노출

Thioacetamide is used as a replacement for hydrogen sulfide in qualitative analyses. Thioacetamide has been used as an organic solvent in the leather, textile, and paper industries; as an accelerator in the vulcanization of buna rubber; and as a stabilizer of motor fuel.

Carcinogenicity

Thioacetamide is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.

운송 방법

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Purification Methods

Crystallise the amide from absolute diethyl ether or *benzene. Dry it at 70o in a vacuum and store it over P2O5 at 0o under nitrogen. (It develops an obnoxious odour on storage, and absorption at 269nm decreases, hence it should be freshly recrystallised before use). [Beilstein 2 IV 565.]

비 호환성

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.

폐기물 처리

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Treatment in an incinerator, boiler or cement kiln.
