Cas no 108338-19-8 (4-NITROPYRIDINE-2-CARBALDEHYDE)

4-Nitropyridine-2-carbaldehyde is a versatile heterocyclic compound featuring both a nitro group and an aldehyde functional group on a pyridine ring. This structure makes it a valuable intermediate in organic synthesis, particularly for the preparation of pharmaceuticals, agrochemicals, and specialty chemicals. The electron-withdrawing nitro group enhances reactivity, facilitating nucleophilic substitution and condensation reactions, while the aldehyde moiety allows for further derivatization. Its well-defined reactivity profile and stability under controlled conditions make it suitable for use in complex multi-step syntheses. The compound is typically handled under standard laboratory conditions, with precautions taken to avoid moisture and excessive heat to maintain purity.
