Application
4'-Chloro-2'-hydroxyacetophenone (CAS 6921-66-0) is a versatile halogenated phenol derivative widely used as a key pharmaceutical intermediate and organic building block. It is the core precursor for synthesizing flufenzine (a GABA antagonist insecticide) and is instrumental in the production of 2-(4-chlorophenyl)benzoxazole, a pharmacophore with potent antimicrobial and antifungal activity. This compound also serves as a critical intermediate in the synthesis of various antifungal agents, including fluconazole analogs, and plays a role in preparing bioactive molecules with anticancer and anti-inflammatory properties. Its unique ortho-hydroxy and para-chloro substitution pattern enables regioselective functionalization, making it a valuable scaffold in medicinal chemistry for constructing heterocyclic libraries. In agrochemical R&D, it is used to develop effective crop protection agents.
