  • Applications

    2,3-Dichloro-1-propene (CAS 78-88-6) is primarily used as an intermediate in organic synthesis, providing a vinyl-chloro building block for downstream transformations. It is commonly employed in the production of chlorinated monomers for specialty polymers and resins, enabling crosslinking and modified reactivity in polymer systems. In coatings and inks, it serves as a reactive precursor for vinyl-functional additives and crosslinkable components. It is also used in adhesives formulations as a reactive comonomer or curing partner, contributing to network formation. Additionally, it may appear in the synthesis of specialty chemicals, including intermediates for agrochemical and pharmaceutical synthesis, depending on formulation and regulatory constraints. Subject to local regulations and formulation limits.
