D-Pantothenic acid-¹³C₃,¹⁵N hemicalcium hemihydrate  (Synonyms: Pantothenate-13C3,15N; Vitamin B5-13C3,15N hemicalcium hemihydrate)

Vitamin B5-¹³C₃,¹⁵N hemicalcium hemihydrate is the ¹³C and ¹⁵N labeled Vitamin B5 hemicalcium hemihydrate^[1].

1. This compound can be used as a tracer.
2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

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^[35].
