Cas 495-18-1 /Benzohydroxamic acid (also known as benzyl hydroxyoxoacetic acid or N-hydroxybenzamide) is an aromatic hydroxyoxoacetic acid organic compound with the molecular formula C₇H₇NO₂ and a molecular weight of 137.14. At room temperature, it appears as white orthorhombic plate-like or needle-like crystals. It is slightly soluble in water but readily soluble in polar solvents such as ethanol and ethyl acetate. Its molecular structure contains a benzene ring and a hydroxamic acid group (-CONHOH), endowing it with strong chelating and reducing properties. It is widely used in mineral flotation, analytical testing, pharmaceutical synthesis, and industrial water treatment.
