Oxaloacetic acid-¹³C₄  (Synonyms: 2-Oxosuccinic acid-¹³C₄)

Oxaloacetic acid-¹³C₄ is the ¹³C-labeled Oxaloacetic acid. Oxaloacetic acid (2-Oxosuccinic acid) is a metabolic intermediate involved in several ways, such as citric acid cycle, gluconeogenesis, the urea cycle, the glyoxylate cycle, amino acid synthesis, and fatty acid synthesis[1][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^[3]
