4-CHLORO-3-NITROBENZYL ALCOHOL

4-Chloro-3-nitrobenzyl alcohol (CAS 55912-20-4) is a high-purity chloro-nitro substituted benzyl alcohol intermediate widely used in pharmaceutical synthesis, organic chemistry research, and fine chemical manufacturing. This compound features a chlorine substituent at the para-position and a nitro group at the meta-position of the benzyl alcohol structure, 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 substitution, and functional group transformations, it exhibits excellent reactivity in catalytic hydrogenation (nitro to amino), esterification, etherification, and cross-coupling pathways. Our product is manufactured under strict quality control standards, ensuring a purity of ≥98%, making it ideal for pharmaceutical manufacturing, medicinal chemistry research, and scale-up production. This compound is particularly valuable in the synthesis of pharmaceuticals containing chloro-nitro aromatic scaffolds, agrochemical intermediates, and specialty chemical precursors. As a reliable benzene derivative intermediate, it serves as an important precursor for constructing functionalized aromatic systems in drug discovery and fine chemical development programs.
