Used primarily in organic synthesis as a reagent for introducing the 3-chloropropyl group into molecules. It is commonly employed in the preparation of pharmaceuticals, agrochemicals, and specialty chemicals. The compound is particularly useful in the synthesis of intermediates for active pharmaceutical ingredients (APIs) due to its ability to form stable covalent bonds. Additionally, it finds application in the production of polymers and coatings, where it acts as a crosslinking agent to enhance material properties. Its reactivity with amines and alcohols makes it valuable in the development of functionalized materials and surface modifiers.
