Application

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:
  • 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

Reducing agent for high performance liquid chromatography analysis of oligosaccharides

Modifier in decant oil affecting its carbonization to mesophase pitch

A sequential reaction methodology is employed for the complete derivatization of protein thiols, amines, and acids in high purity under denaturing conditions. Following standard thiol alkylation, protein amines are modified via reductive methylation with formaldehyde and pyridine-borane. Protein acids are
