column was used to separate the components of a mixture of the pyridylamino derivatives of oligosaccharides from mono- to dodeca-saccharide in 20 min. A neutral fluorescent by-product, formed in all reductive aminations, was identified as (2-amino-1-pyridyl)cyanoborane and was eluted well before monosaccharide derivatives and thus did not interfere with the analysis.
