4-Methyl-3-nitropyridine

4-Methyl-3-nitropyridine (CAS 5832-44-0), also known as 3-Nitro-4-methylpyridine or Pyridine, 4-methyl-3-nitro-, is a high-purity nitro-methyl substituted pyridine intermediate widely used in pharmaceutical synthesis, organic chemistry research, agrochemical development, and fine chemical manufacturing. This compound features a methyl substituent at the 4-position and a nitro group at the 3-position of the pyridine ring, making it a versatile building block for the development of complex organic molecules and active pharmaceutical ingredients (APIs). As a key intermediate in reduction reactions, nucleophilic aromatic substitution, and heterocyclic functionalization, it exhibits excellent reactivity in catalytic hydrogenation (nitro to amino), cross-coupling reactions, and electrophilic aromatic substitution pathways. Our product is manufactured under strict quality control standards, ensuring a purity of ≥98%, making it ideal for pharmaceutical manufacturing, medicinal chemistry research, kinase inhibitor synthesis, and scale-up production. This compound is particularly valuable in the synthesis of pharmaceuticals containing nitromethylpyridine scaffolds, heterocyclic kinase inhibitor intermediates, agrochemical precursors, and specialty chemical precursors. As a reliable pyridine derivative intermediate from our product line, it serves as an important precursor for constructing functionalized nitrogenous heterocyclic systems in drug discovery and fine chemical development programs.
