Application Scenarios
Organic Synthesis & Catalysis – Widely used to facilitate classic organic reactions including Horner–Wadsworth–Emmons olefination, aldol condensation, Mizoroki–Heck cyclization and Tsuji–Trost cascade reactions. It supports the synthesis of chiral amino acids, natural derivatives such as Leiodolide A, and cycloalkanoindoline compounds.
Polymer & Material Industry – Acts as a high-efficiency curing accelerator for epoxy and fluororubber materials, and catalyzes solid-state polycondensation for thiophene monomer preparation. It also serves as a functional reagent in industrial dyeing processes.
Biomedical Research – Applied as a key synthetic intermediate and antiviral raw material, supporting pharmaceutical molecule development and related biomedical studies.
