O-(N-Succinimidyl)-1,1,3,3-tetramethyluronium tetrafluoroborate (TSTU) (CAS: 105832-38-0) is a premium coupling reagent and highly specialized intermediate essential for advanced bioconjugation and peptide synthesis. This highly efficient uronium salt is primarily utilized for the rapid and stable preparation of active N-hydroxysuccinimide (NHS) esters from carboxylic acids. Manufactured under stringent quality control protocols, our industrial-grade TSTU ensures superior chemical stability, exceptional reactivity, and reliable batch-to-batch consistency. It serves as a critical component for sophisticated biochemical research, protein modification, and large-scale pharmaceutical manufacturing.
