Used as a versatile alkylating agent in organic synthesis, particularly in the preparation of functionalized benzotriazole derivatives. Its reactivity stems from the bromomethyl group, which readily undergoes nucleophilic substitution reactions. It is commonly employed in medicinal chemistry to link benzotriazole moieties to other molecular frameworks, enhancing biological activity or modifying pharmacokinetic properties. Also utilized in the development of agrochemicals and as a building block in the synthesis of fluorescent probes and coordination compounds due to the benzotriazole unit’s ability to participate in hydrogen bonding and metal coordination.
