An amidoxime is an organic chemical compound containing both a hydroxyimino (═NOH) and an amino (—NH₂) group attached to the same carbon atom. Its general formula is R-C(NH₂)═NOH. Amidoximes are important versatile building blocks in organic synthesis, used to create other complex molecules, particularly heterocycles. They are also valued for their ability to chelate (bind) metal ions, making them useful in processes like extracting trace metals such as uranium from seawater and as adsorbents for heavy metal pollutants from water.
