1,7-Dimethylxanthine-2,4,5,6-13C4-1,3,9-15N3 is a labeled form of 1,7-dimethylxanthine, which is also known as caffeine. In this labeled version, specific carbon and nitrogen atoms are replaced with stable isotopes, namely carbon-13 (13C) and nitrogen-15 (15N). These isotopes are used to trace the metabolic fate and behavior of caffeine in biological systems. Paraxanthine, or 1,7-dimethylxanthine, is a natural metabolite derived from theophylline and theobromine, which are found in coffee, tea, and chocolate.
