对氯苯甲醛是一种重要的有机合成中间体,在农药、医药、染料及其他有机合成中具有广泛的用途.对氯苯甲醛和频哪酮反应生成烯酮,再经加氢、溴化和三唑反应,最后用硼氢化钠还原制得的多效唑,是一种植物生长调节剂;以对氯苯甲醛为原料还可合成除草剂麦敌散.对氯苯甲醛与巯基丙酸、高锰酸钾等反应制得的芬那露用作弱安定药,具有镇静、安定和中枢性肌肉松驰的作用.以对氯苯甲醛为原料制得的染料可用于羊毛、蚕丝、锦纶等织物以及皮革羽毛等的染色.
P-chlorobenzaldehyde is an important organic synthesis intermediate and has a wide range of uses in pesticides, pharmaceuticals, dyes and other organic synthesis. P-chlorobenzaldehyde and pinacolone react to form ketene, followed by hydrogenation and bromination. And triazole reaction, and finally with borohydride reduction of paclobutrazol, is a plant growth regulator; to chlorobenzaldehyde as raw material can also be synthesized herbicide Mai enemy scattered. P-chlorobenzaldehyde and mercaptopropionic acid, high Potassium manganate and other reaction products are used as weak stabilizers, which have the effects of sedation, stability and central muscle relaxation. The dyes prepared from p-chlorobenzaldehyde can be used for wool, silk, nylon and other fabrics. And the dyeing of leather feathers.
