Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of anticoagulant drugs and antifungal agents. It serves as a building block in organic reactions due to the presence of aldehyde and phenolic functional groups, enabling the formation of Schiff bases and other derivatives. Also applied in the development of agrochemicals and dyes, where its chloro and methoxy substituents influence reactivity and stability. Its structure supports chelation with metal ions, making it useful in coordination chemistry for catalyst design.
