What is Borane-triethylamine?

Borane-triethylamine (CAS 1722-26-5), also referred to as triethylamine borane, is a stable, handleable boron-hydrogen complex used as a controlled source of borane in synthetic and industrial chemistry.

Where is Borane-triethylamine used?

  • Pharmaceutical synthesis: selective reducing agent and hydroboration reagent for chiral intermediates and active pharmaceutical ingredients
  • Polymer manufacturing: radical polymerization initiator for acrylates and other vinyl monomers
  • Electronics: production of boron-containing specialty materials and surface modification for semiconductor fabrication
  • Biotechnology: nucleotide chemistry and oligonucleotide synthesis
  • It delivers reducing and borylating reactivity without the hazards of free diborane gas.

Commercial specifications

  • Liquid, neat or in solution with compatible solvents such as THF
  • Research quantities through to bulk industrial volumes
  • Technical and high-purity grades
