  • Applications

    2,2'-Dithiodibenzoyl chloride (CAS 19602-82-5) is a difunctional acyl chloride containing a disulfide bridge, used to introduce cleavable disulfide linkages in polymer and coating chemistries. As a diacyl chloride intermediate, it commonly acts as a difunctional crosslinker for polymer networks or coatings, enabling bisamide or bisester connections with diamines or diols and thereby forming crosslinked materials. It is also employed as a synthetic intermediate to install disulfide-containing functionalities, for example by linking benzoyl groups to substrates or within bisamide architectures. In surface modification and adhesive formulations, it can graft disulfide-bearing moieties onto substrates via amide bond formation. In addition, it may serve as a starting point to prepare disulfide-containing compounds and functional materials for specialty coatings and electronics, with use subject to formulation conditions and local regulations.
