Application

Sodium bicarbonate-13C can be used:
  • As a probe for NMR− and MRI− based pH imaging.
  • To predict the reaction mechanism in selective hydrogenation of bicarbonate to formate, catalyzed by a ruthenium(III) complex.
  • For 13C labeling of amino acid sample for compound-specific stable isotope analysis (CSIA).
