4-Aminophenylarsonic acid is an arsenic-containing aromatic organic compound consisting of a benzene ring, a para-amino group (-NH₂), and an arsonic acid group (-AsO(OH)₂). It exhibits antibacterial activity against colistin-susceptible Klebsiella pneumoniae. Combining the chemical properties of organic arsenic with the reactivity of amino groups, it can be used to prepare affinity chromatography resins, targeted drug carriers, and functional nanomaterials.
