24dichlorophenyl
24dichlorophenyl, commonly written as 2,4-dichlorophenyl, is the phenyl substituent bearing chlorine atoms at the 2 and 4 positions of the benzene ring. As a substituent, it is attached to a larger molecule through the ring carbon at the point of connection, and has the approximate formula C6H3Cl2-. The presence of chlorine atoms makes the ring more electron-withdrawing and lipophilic compared with the unsubstituted phenyl group, influencing reactivity, potency, and metabolic stability in downstream compounds. The 2,4-dichlorophenyl group occurs in a range of industrial and pharmaceutical chemicals; notably, it is the aryl portion of the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) and is found in various dyes, polymers, and agrochemical intermediates.
In terms of properties, derivatives vary, but compounds containing the 2,4-dichlorophenyl moiety typically show limited water
