  • Applications

    1-Butylpyrrolidine (CAS 767-10-2) is used primarily as a polar aprotic solvent in industrial manufacturing and as an intermediate for the synthesis of specialty chemicals; in the polymer and plastics sector, coatings, and adhesives it serves as a solvent or processing additive; it is also employed as a cleaning solvent in industrial maintenance; and due to its mild basicity, it can function as a catalyst or additive in polyurethane and epoxy formulations.
