4-Methylpentanoic acid-d₁₁ 

4-Methylpentanoic acid-d₁₁ (Isocaproic Acid-d₁₁) is the deuterium labeled 4-Methylpentanoic acid. 4-Methylpentanoic acid is a short-chain fatty acid and a metabolite of 20 α-hydroxycholesterol (HY-12316) that can be detected in feces. The concentration of 4-Methylpentanoic acid is closely associated with several diseases, such as depression. 4-Methylpentanoic acid is also applicable to studies on cholesterol metabolism.

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^[1].
