4-Formyl-2-nitrophenol (Cat No.: R017739) is an aromatic compound consisting of a phenol ring substituted with a nitro group at the 2-position and a formyl (aldehyde) group at the 4-position. This molecule exhibits both electron-donating (hydroxyl) and electron-withdrawing (nitro and formyl) groups, giving it unique reactivity in electrophilic and nucleophilic aromatic substitution reactions. It is used as an intermediate in the synthesis of dyes, pharmaceuticals, and fine chemicals. Its functional groups also make it valuable in coordination chemistry and Schiff base formation.
