General description

Arsenic(III) oxide, also known as arsenic trioxide, is an amphoteric oxide that serves as a raw material for the synthesis of several arsenic-based compounds. It is utilized to decolorize glasses and enamels. Its efficacy in treating in acute promyelocytic leukaemia (APL) has been investigated.

Application

Arsenic(III) oxide was used in a study detailing the effect of arsenic trioxide in combination with γ-irradiation to elucidate the hemoglobin (Hb).

Biochem/physiol Actions

Very potent agent against acute promyelocytic leukemia (APL). Causes skin, lung and bladder cancer.
