3Hydroxyisoxazole

3-Hydroxyisoxazole is a heterocyclic organic compound with the chemical formula C3H3NO2. It belongs to the isoxazole class of compounds, which are five-membered rings containing one nitrogen atom and one oxygen atom adjacent to each other. In 3-hydroxyisoxazole, a hydroxyl group is attached to the carbon atom at the 3-position of the isoxazole ring.

This compound exists in tautomeric forms due to the presence of the hydroxyl group adjacent to the ring nitrogen. It can exist as the 3-hydroxy tautomer or the 3-oxo tautomer (isoxazol-3(2H)-one). The relative stability of these tautomers can depend on factors such as solvent and pH.

3-Hydroxyisoxazole and its derivatives have been explored for various applications in organic synthesis and medicinal chemistry. They can serve as building blocks for the construction of more complex molecules. The isoxazole ring system itself is found in a range of biologically active compounds, and the introduction of a hydroxyl group at the 3-position can influence the compound's reactivity and biological properties. Research has investigated its potential in areas such as agrochemicals and pharmaceuticals, although specific widespread commercial applications may be limited or specialized.
