Overview
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.
It delivers reducing and borylating reactivity without the hazards associated with free diborane gas, making it a practical reagent for large-scale operations in various chemical sectors.
In pharmaceutical synthesis, it functions as a selective reducing agent and hydroboration reagent for producing chiral intermediates and active pharmaceutical ingredients where precise stereochemical control is required.
Polymer manufacturers use it as a radical polymerization initiator, particularly for initiating polymerization of acrylates and other vinyl monomers under mild conditions for specialized material production.
In electronics, it supports the production of boron-containing specialty materials and surface modification processes relevant to semiconductor fabrication and advanced component manufacturing.
Biotechnology applications include its use in nucleotide chemistry and oligonucleotide synthesis, where controlled borane transfer is needed without side reactions from more reactive boron sources.
Borane-triethylamine is supplied as a liquid, typically as a neat reagent or in solution with compatible solvents such as THF, ensuring ease of handling during industrial processes.
It is available in research quantities through to bulk industrial volumes, with technical and high-purity grades offered to meet pharmaceutical and electronic manufacturing specifications.
