Description

Dodecanoic-12,12,12-D3 Acid is a deuterium-labeled isotopologue of lauric acid, a saturated medium-chain fatty acid. This compound is a critical tool in analytical chemistry and life sciences research, where it serves as a stable, non-radioactive internal standard for mass spectrometry and metabolic studies. It is essential for researchers and quality control laboratories in the pharmaceutical, nutritional science, and biochemistry sectors who require precise quantification and tracing of lauric acid and its derivatives.

Application

• Mass Spectrometry Internal Standard: Used as a quantitative reference standard in GC-MS and LC-MS analyses for accurate measurement of lauric acid in complex biological and chemical matrices.
• Metabolic Pathway Tracing: Enables the study of lipid metabolism, absorption, and β-oxidation in nutritional and pharmacological research without isotopic interference.
• Pharmaceutical Development: Supports drug metabolism and pharmacokinetics (DMPK) studies for compounds involving fatty acid pathways.
• Biochemical Research: Acts as a labeled precursor or probe in enzymatic studies and the biosynthesis of more complex labeled lipids.
• Quality Control & Reference Material: Serves as a certified reference material (CRM) for calibrating analytical instruments and validating methods in analytical laboratories.
