Used primarily as an intermediate in organic synthesis, this compound serves in the preparation of pharmaceuticals and agrochemicals. Its reactive carbonyl chloride group readily forms amide or ester derivatives, making it valuable for constructing complex molecules. It is particularly useful in the development of bioactive compounds where the benzotriazole moiety acts as a pharmacophore or stabilizing element. Additionally, it can function as a coupling agent in peptide-like synthesis or in the modification of biomolecules due to its selective reactivity under mild conditions.
