Arsanilic acid

[1] Arsanilic acid saw long use as a veterinary feed additive promoting growth and to prevent or treat dysentery in poultry and swine.

[5] Still sometimes used in laboratories,[6] arsanilic acid's legacy is principally through its influence on Paul Ehrlich in launching the antimicrobial chemotherapy approach to treating infectious diseases of humans.

[11] In 1859, in France, while developing aniline dyes,[13] Antoine Béchamp synthesized a chemical that he identified, if incorrectly, as arsenic acid anilide.

)[14][16] Soon, however, Robert Koch found through an Atoxyl trial in German East Africa that some 2% of patients were blinded via atrophy of the optic nerve.

[11] Arsanilic acid gained use as a feed additive for poultry and swine to promote growth and prevent or treat dysentery.

E.g. water Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
