Hydroxamic acids are a class of organic compounds that contain the functional group R-C(=O)N(R')OH. In this structure, R and R' represent organic substituents, and the central carbon is double-bonded to an oxygen and single-bonded to a nitrogen atom which is also bonded to a hydroxyl group. They are generally considered weak acids, with their acidity primarily due to the hydroxyl proton.

These compounds can be synthesized through various methods, often involving the reaction of esters or acid chlorides with hydroxylamines. Hydroxamic acids exhibit a range of chemical properties, including the ability to chelate metal ions. This chelating ability is particularly significant and has led to their investigation and application in various fields.

One notable application of hydroxamic acids is in medicine, particularly as enzyme inhibitors. For example, they have been developed as inhibitors of metalloproteinases, which are enzymes implicated in diseases such as cancer and arthritis. Certain hydroxamic acids also possess antibiotic and antifungal properties. Beyond medicinal chemistry, hydroxamic acids find use as corrosion inhibitors, as reagents in analytical chemistry, and in the extraction of metals. Their diverse reactivity and metal-binding capabilities make them versatile molecules in organic and inorganic chemistry.
