3-Ethylbenzothiazolium bromide（Cat No.:L030217）is a quaternary ammonium salt composed of a benzothiazole ring substituted with an ethyl group at the 3-position and paired with a bromide counterion. This compound is commonly used as a reactive intermediate or phase-transfer catalyst in organic synthesis. Its positively charged nitrogen within the heterocyclic ring enhances solubility in polar solvents and facilitates electrophilic reactivity. It plays a role in the preparation of cyanine dyes, ionic liquids, and other sulfur- and nitrogen-containing functional materials. Its structure also supports research in photochemistry, sensor development, and materials science.
