Applicazioni
Borane pyridine complex is commonly used as a reducing reagent for the reductive amination of aldehydes and ketones. It is the precursor to synthesize carbon-based material, BC4N. Along with iodine, it can be used as a reagent for hydroboration of alkenes and alkynes.
Used for:
Reducing agent for high performance liquid chromatography analysis of oligosaccharides
Modifier in decant oil affecting its carbonization to mesophase pitch
- Investigations of site energy distribution functions from Toth isotherm for adsorption of gases on heterogeneous surfaces
- Preparation of α−alkyl-β-hydroxy esters
- Regioselective immobilization of short oligonucleotides to acrylic copolymer gels
- Preparation of Igs conjugated with viral peptide epitopes
- Sintering of silicon carbide

In this note, we describe a method devised to detect, by means of mass spectrometry (MS), tryptophan-containing peptides and proteins using pyridine-borane. This reagent selectively reduces tryptophan residues, converting them to 2,3-dihydro-tryptophan, thereby enabling quantitation of tryptophans.

Methylotrophy, the ability of microorganisms to grow on reduced one-carbon substrates such as methane or methanol, is a feature of various bacterial species. The prevailing oxidation pathway depends on tetrahydromethanopterin (H4MPT) and methylofuran (MYFR), an analog of methanofuran from methanogenic
