L-Aspartic acid-¹³C₄,¹⁵N is the ¹³C-labeled and ¹⁵N-labeled L-Aspartic acid. L-Aspartic acid is is an amino acid, shown to be a suitable proagent for colon-specific agent deliverly.

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.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.
