Butanedioic acid-13C2

Butanedioic acid-13C2 is the 13C labeled Succinic acid[1]. Succinic acid is a potent and orally active anxiolytic agent. Succinic acid is an intermediate product of the tricarboxylic acid cycle. Succinic acid can be used as a precursor of many industrially important chemicals in food, chemical and pharmaceutical industries[2][3].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
