3-Chlorophenol is an organic compound with the molecular formula C6H4ClOH. It is one of three isomers of monochlorophenol. It is a colorless or white solid that melts easily and exhibits significant solubility in water. Together with 3,5-dichlorophenol, it is prepared industrially by dechlorination of polychlorophenols. Alternatively, it arises via the cumene process, which starts with the alkylation of chlorobenzene with propylene.[6]
