Arsanilic Acid Raw Materials

Arsanilic acid, also known as aminophenyl arsenic acid or aminophenyl arsonic acid, is an organoarsenic compound, an amino derivative of phenylarsonic acid whose amine group is in the 4-position. A crystalline powder introduced medically in the late 19th century as Atoxyl, its sodium salt was used by injection in the early 20th century as the first organic arsenical drug for human patients, but was soon found prohibitively toxic. Eventually it became, and is still used as, an antibacterial veterinary feed additive to promote growth and prevent or treat dysentery in poultry and swine.
