Abstract

7865. Farbwerke vorm. Meister, Lucius, &. Br³ning. May 17, 1911, [Convention date]. 3:3<1>-Diamino-4:4<1>-dioxyarsenobenzene-formaldehyde sulphoxylate is produced by treating an aqueous suspension of the base, or an aqueous solution of one of its salts, with formaldehyde sulphoxylate. The product dissolves in alkali solutions, from which acids precipitate the free acid containing either one or two acid groups according to the precipitation temperature. The alkali solutions are useful in therapeutics.
