2-Hydroxypyridine（Cat No.:R004382）, also known as 2-pyridinol, is a heterocyclic aromatic compound featuring a hydroxyl group at the 2-position of a pyridine ring. It exists in equilibrium with its tautomeric form, 2-pyridone, where the hydroxyl proton shifts to form a keto group. This tautomerism significantly influences its chemical behavior and hydrogen bonding properties. 2-Hydroxypyridine is used as a building block in pharmaceuticals, agrochemicals, and coordination chemistry. It serves as a ligand in metal complexes and plays a role in designing biologically active molecules due to its versatile reactivity and structural similarity to nucleobases.
