Description

Pentanoic-4,4-D2 Acid is a deuterium-labeled derivative of valeric acid, where two hydrogen atoms at the 4-position are replaced with deuterium. This isotopic labeling makes it a critical tool in advanced analytical chemistry and metabolic research, providing a stable, non-radioactive tracer. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries for applications such as internal standards in mass spectrometry, reaction mechanism studies, and the synthesis of labeled compounds.

Application

• As a stable isotopic internal standard for the accurate quantification of valeric acid and related metabolites in biological samples via GC-MS or LC-MS.
• In pharmaceutical research for drug metabolism and pharmacokinetic (DMPK) studies to trace the metabolic pathways of drug candidates.
• As a precursor or building block in the synthesis of more complex deuterium-labeled compounds for use in spectroscopy and mechanistic studies.
• For NMR spectroscopy applications, where deuterium labeling is used to simplify spectra and study molecular structure and dynamics.
• In material science research to investigate polymer properties and degradation mechanisms using isotopic tracing.
• Within agrochemical development to study the environmental fate, metabolism, and residue analysis of pesticides and herbicides.
