What is Morpholineborane?

Morpholineborane (CAS 4856-95-5), also referenced commercially as Borane-morpholine, is a stable, handleable borane complex used as a controlled source of borane in synthetic chemistry.

Where is Morpholineborane used?

  • Pharmaceutical manufacturing: selective reducing agent for active pharmaceutical ingredients
  • Electronics: electroless plating and surface metallization with controlled boron deposition onto substrates
  • Polymer chemistry: radical polymerization initiator under mild conditions
  • Organoboron chemistry: boron source for hydroboration in fine chemical intermediates
  • It delivers reducing and borating reactivity where free borane gas would be impractical or hazardous to handle.

Commercial specifications

  • Reagent and high-purity grades suited to pharmaceutical synthesis and electronics
  • Packaging in research-scale quantities through to larger commercial volumes
