Used primarily as an intermediate in organic synthesis, this compound serves in the preparation of functionalized polymers and specialty chemicals. Its reactive chloropropyl group allows for further alkylation or coupling reactions, making it valuable in the development of surfactants, pharmaceuticals, and agrochemicals. It is also employed in the modification of resins and coatings to enhance crosslinking and thermal stability. Due to the presence of the sulfonate ester, it can act as a leaving group in nucleophilic substitution reactions, facilitating the introduction of propyl spacers with terminal chlorine in complex molecules.
