Cas no 15128-89-9 (4-Methyl-2-nitropyridin-3-ol)

4-Methyl-2-nitropyridin-3-ol is a nitropyridine derivative characterized by the presence of a methyl group at the 4-position and a nitro group at the 2-position of the pyridine ring, with a hydroxyl substituent at the 3-position. This compound serves as a versatile intermediate in organic synthesis, particularly in the preparation of pharmaceuticals, agrochemicals, and specialty chemicals. Its structural features enable selective functionalization, making it valuable for constructing complex heterocyclic frameworks. The electron-withdrawing nitro group enhances reactivity in nucleophilic substitution reactions, while the hydroxyl group offers additional sites for derivatization. The compound is typically handled under controlled conditions due to its potential sensitivity.
