TCI C0239 4-Chlorophenetole (CAS 622-61-7) is the para isomer of chlorophenetole, combining an ethoxy group with an aromatic chlorine on the same ring. The electron-donating ethoxy group influences ring reactivity, while the aryl chloride offers a handle for transition-metal-catalyzed cross-coupling. Its symmetric substitution pattern often simplifies purification of downstream derivatives. AMI Scientific supplies this TCI building block in a 25 g pack suited to research-scale synthesis.
