Used primarily as an alkylating agent in organic synthesis, enabling the introduction of chloroethyl groups into molecules for pharmaceutical and agrochemical development. It serves as an intermediate in the production of vinyl monomers, particularly vinyl acetate derivatives used in polymer manufacturing. Also employed in the synthesis of choline chloride, an essential nutrient in animal feed. Its reactivity makes it valuable in creating ester-based compounds for fragrances and specialty solvents. Due to its volatility and reactivity, it is handled with care in controlled environments.
