Description

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

Caution

May darken in storage.

Other Notes

may contain excess pyridine
