• Tetrachlorvinphos

(Z)-2-클로로-1-(2,4,5-트리클로로페닐)비닐 디메틸 인산염 화학적 특성, 용도, 생산

• 개요

  Tetrachlorvinphos was initially registered for use in the United States in 1966 for use on various food crops, livestock, and pet animals, and in around buildings. Its use on food crops were voluntarily canceled in the United States in 1987; however, it is used on food crops in developing countries. Tetrachlorvinphos is sold under the trade names Rabon and Gardona.

• 화학적 성질

  Technical tetrachlorvinphos is a tan-to-brown crystalline solid. Tetrachlorvinphos is stable at ,100 C and slowly hydrolyzed at 50°C. Aromatic odor.
  Soluble in water at 24°C 15 ppm; limited solubility in most aromatic hydrocarbons.

• 용도

  Tetrachlorvinphos is used to control lepidopterous and dipterous larvae in fruit and lepidopterous larvae in cotton, maize, rice, tobacco and vegetables. It is also used against nuisance flies in animal houses, animal ectoparasites and stored product pests.

• 위험도

  Cholinesterase inhibitor. Questionable carcinogen.

• Carcinogenicity

  When rats were given diets with 0, 4250, or 8500 ppm tetrachlorvinphos for 80 weeks, both males and females had a high incidence of thyroid C-cell hyperplasia, and females had increased incidences of adrenal cortical adenomas and thyroid C-cell adenomas .

• 환경귀착

  Tetrachlorvinphos is nonpersistent in the environment. The primary route of dissipation is through biotic degradation. Based on its use pattern, risks of contamination of groundwater or surface water by tetrachlorvinphos are minimal.

• 신진 대사 경로

  The chemical structure of tetrachlorvinphos is very close to that of chlorfenvinphos and the routes of metabolic breakdown have been shown to be very similar. Technical tetrachlorvinphos is usually >95% Z-isomer, unlike chlorfenvinphos which is an E/Z mixture. As with chlorfenvinphos, the major routes of detoxification are by dealkylation and hydrolysis to yield desmethyltetrachlorvinphos and 2,2’,4’,5’- tetrachloroacetophenone plus dimethyl phosphate, respectively. Further metabolism of the chloroacetophenone moiety then leads, via reduction or hydrolysis and glutathione-dependent displacement of the side chain chlorine substituent, to the formation of 1-(2,4,5-trichlophenyl) ethane-l,Z-diol and 1-(2,4,5-trichlorophenyl)ethan-l-owl hich are conjugated with glucose or glucuronic acid to afford the ultimate metabolites. Oxidation of the β carbon atom to give 2,4,5-trichloromandelic acid followed by decarboxylation leads to the formation of 2,4,5-trichlorobenzoic acid which is conjugated with glycine in some mammals as the final metabolite. The metabolic routes were summarised by Beynon et al. (1973).
