General description

Cellobiose is a disaccharide, commonly classified as a reducing sugar. It is mostly produced as an intermediate in the hydrolysis of the polysaccharide cellulose.

Application

D-(+)-Cellobiose may be used as an analytical standard in the following:
  • Training, testing, and external validation of the gradient retention model developed in ion chromatography using the artificial intelligence-quantitative structure retention relationship (QSRR) model approach.
  • Amperometric detection of the analyte in anion-exchange chromatography using copper/cupric oxide nanostructured electrode.

D-(+)-Cellobiose may be used as an analytical reference standard for the quantification of the analyte in caramel samples using gas–liquid chromatography coupled to mass spectrometry (GLC–MS).
