(4-Hydroxyphenyl)arsonic acid

Description:

(4-Hydroxyphenyl)arsonic acid, also known as Roxarsone, is an organoarsenic compound characterized by its aromatic structure featuring a hydroxyl group and an arsenic atom. It appears as a white to off-white crystalline solid and is soluble in water, which facilitates its use in various applications. This compound is primarily recognized for its role as a veterinary drug and feed additive, particularly in poultry, where it has been used to promote growth and prevent disease. However, due to concerns regarding arsenic toxicity and environmental impact, its use has been scrutinized and regulated in many regions. The compound exhibits properties typical of both phenolic and organoarsenic substances, including potential reactivity with nucleophiles and the ability to form complexes with metal ions. Its chemical structure allows for various reactions, including oxidation and substitution, which can lead to the formation of different derivatives. Safety considerations are paramount when handling this substance, as arsenic compounds are known for their toxicity and potential carcinogenic effects.
