  • Applications

    Bromoethane (CAS 74-96-4) is primarily used as an alkylating reagent in organic synthesis, enabling the introduction of ethyl groups to form ethers, esters, and other derivatives; it also serves as an industrial intermediate in the manufacture of pharmaceutical and agrochemical compounds, and historically has been employed as a fumigant for soil and stored-product pests in agriculture under regulatory controls; in certain processes it functions as a solvent or reaction medium, and it can act as a precursor for specialty polymers, coatings, and adhesive formulations where ethylation chemistry is required.
