TCI 1-(Chloromethyl)-1H-benzotriazole (CAS 54187-96-1) combines a benzotriazole heterocycle with a reactive chloromethyl group at N-1. It is used to install a benzotriazolylmethyl unit onto nucleophiles, where the benzotriazole moiety acts as a removable synthetic auxiliary and leaving group. This strategy helps chemists control reactivity and regioselectivity in multi-step organic synthesis. AMI Scientific supplies 5 g and 25 g packs; keep tightly sealed away from moisture and follow the manufacturer's Safety Data Sheet.
