Tri-sec-butylborane

Tri-sec-butylborane (CAS 1113-78-6) is a trialkylborane compound used as a radical initiator and catalyst precursor in controlled polymerization and synthetic chemistry. It functions by generating carbon-centered radicals under mild conditions.

This chemical enables precise reaction initiation without the thermal requirements of conventional initiators. In polymer chemistry, it initiates radical polymerization of acrylates, methacrylates, and vinyl monomers.

The compound supports the production of specialty plastics and adhesive systems. Pharmaceutical synthesis relies on it as a boron-based reagent for hydroboration and stereoselective carbon–carbon bond-forming reactions.

It is essential in active pharmaceutical ingredient manufacturing and biotechnology research. Scientists use it in the preparation of functional polymers for drug delivery scaffolds and surface modification applications.

It also serves as a catalyst precursor in transition-metal-catalyzed processes where controlled generation of reactive intermediates is required. The material is supplied as a liquid, typically as a solution.

Common solvents include tetrahydrofuran or hexane at defined molar concentrations. It is handled and packaged under inert atmosphere conditions due to its air sensitivity, with supply quantities ranging from laboratory-scale to bulk.

Material is generally available at reagent and synthesis grade, with specifications confirmed by titration or NMR assay. This ensures high performance in sensitive industrial and laboratory chemical processes.
