Inosinic acid-¹⁵N₄ dilithium  (Synonyms: 5'-IMP¹⁵N₄ dilithium; IMP-¹⁵N₄ dilithium; Inosine 5'-dihydrogen phosphate-¹⁵N₄ dilithium)

Inosinic acid-¹⁵N₄ dilithium (5'-IMP-15N4 (dilithium); IMP-15N4 (dilithium); Inosine 5'-(dihydrogen phosphate)-15N4 (dilithium)) is ¹⁵N-labeled Inosinic acid (HY-108213). Inosinic acid is an endogenous metabolite^[1][2].

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].
