Literature References: An organic compd of arsenic yielding inorganic, trivalent arsenic in the body (is excreted partly unchanged, also yields dimethylarsine oxide). Prepd by the distillation of a mixture of arsenic trioxide and potassium acetate which yields Cadet's liquid, contg mostly dimethylarsine oxide. This is oxidized with mercuric oxide yielding crystals of cacodylic acid which is neutralized with Na2CO3 or NaOH: Cadet de Gassicourt, Mem. savants étrangers 3, 633 (1760); Valeur, Gaillot, Compt. Rend. 185, 956 (1927). Use in treatment of psoriasis: S. I. Dawes, H. C. Jackson, J. Am. Med. Assoc. 48, 2020 (1903). Metabolism and excretion: A. Heffter, Arch. Exp. Pathol. Pharmakol. 46, 230 (1901). Use as herbicide: M. A. Sprague, US 3056663 (1962 to Ansul). Possible use in radiation dosimetry: H. S. Levinson, E. B. Garber, Nature 207, 751 (1965).
