| Abstract | CBET-1 is a high-purity certified reference material (CRM) of [13CO]-arsenobetaine bromide from the National Research Council of Canada (NRC), intended for analytical method development and accurate quantitation of arsenobetaine. A unit of this material consists of approximately 30 mg. Certified and information values are based on results from data generated at NRC using quantitative proton nuclear magnetic resonance spectroscopy (1H-qNMR) and chemical specifications. |
