o-Arsanilic acid

Description:

o-Arsanilic acid, also known as 2-Arsanilic acid, is an organoarsenic compound characterized by the presence of an amino group (-NH2) and an arsonic acid group (-As(OH)2) attached to a benzene ring. This compound is typically a white to off-white crystalline solid that is soluble in water and exhibits acidic properties due to the presence of the arsonic acid functional group. It is primarily used in the synthesis of various organic compounds and has applications in agriculture, particularly as a feed additive in livestock for growth promotion and disease prevention. However, due to concerns regarding arsenic toxicity and environmental impact, its use is regulated in many regions. The compound can undergo various chemical reactions, including oxidation and substitution, making it a versatile intermediate in organic synthesis. Safety precautions are essential when handling o-Arsanilic acid, as arsenic compounds can pose significant health risks.

o-Arsanilic acid

CAS: 2045-00-3

o-Arsanilic acid is similar to p-arsanilic acid (once widely used to treat trypanosomiasis). o-Arsanilic acid use, however, has a different application nowadays - it is used for the determination of arsenic levels, particularly in urine. Another interesting application of o-arsanilic acid is to track the binding of labeled anti-cross-reactive idiotype(CRI) preparations to a CRI+ hybridoma proteins.
