Used as a key intermediate in the synthesis of triazole-based pharmaceuticals, particularly antifungal and antiviral agents. Its reactivity allows for the introduction of the 1,2,4-triazole ring into larger molecules, which is a common structural motif in drugs targeting fungal cytochrome P450 enzymes. Also employed in agrochemicals for the development of fungicides and plant growth regulators. The chloromethyl group facilitates alkylation reactions, making it valuable in heterocyclic chemistry for building complex bioactive molecules.
