Hydroxamic acids are a class of organic compounds that contain the functional group R-C(=O)N(R')OH, where R and R' can be hydrogen or organic substituents. They are characterized by the presence of a hydroxyl group attached to the nitrogen atom of an amide. Hydroxamic acids are generally weak acids and can form complexes with various metal ions.

The synthesis of hydroxamic acids can be achieved through several methods, including the reaction of esters with hydroxylamine, or the reaction of acyl halides with N-substituted hydroxylamines. They are found naturally in some microorganisms and plants and play roles in biological processes. For example, some hydroxamic acids act as siderophores, which are compounds that chelate iron and facilitate its uptake by cells.

Industrially, hydroxamic acids have found applications as corrosion inhibitors, particularly in acidic environments. Their ability to bind to metal surfaces forms a protective layer. Furthermore, some hydroxamic acid derivatives have been investigated for their medicinal properties, including use as enzyme inhibitors, notably for histone deacetylases (HDACs), which are targets in cancer therapy. Their chemical reactivity also makes them useful intermediates in organic synthesis.
