4-Amino-2-chlorophenol (4A2CP) is a chlorinated aniline. Nephrotoxic potential of 4-amino-2-chlorophenol and its comparison with 4-aminophenol, 4-amino-2-chlorophenol, 4-amino-3-chlorophenol and 4-amino-2,6-dichlorophenol using isolated renal cortical cells from male Fischer 344 rats has been investigated. -Amino-2-chlorophenol may be used in the synthesis of the following compounds: . N-(3-chloro-4-hydroxyphenyl)-N′,N′-dimethylurea . 1,4-diketo-3-((4-[N-(3-chloro-4-hydroxyphenyl)amino]sulfonyl)phenyl)-6-phenylpyrrolo[3,4-c]pyrrole, a novel fluorescent pH-i
