Description

Hexadecanoic Acid-1-13C is a stable isotope-labeled analog of palmitic acid, where the carbon-13 isotope is incorporated at the carboxyl position. This precise labeling is critical for applications requiring high-fidelity metabolic and biochemical tracing, offering unparalleled accuracy in research and analysis. It is an essential tool for scientists and quality control professionals in the pharmaceutical, nutritional science, and advanced materials research sectors who require definitive tracking of fatty acid pathways and synthesis.

Application

• Metabolic Pathway Tracing: Used as an internal standard in mass spectrometry (GC-MS, LC-MS) for quantitative analysis and to study β-oxidation and lipid biosynthesis.
• Pharmaceutical Research & Development: Employed in drug metabolism and pharmacokinetics (DMPK) studies to track the fate of drug compounds and their lipid-based formulations.
• Nutritional Science: Facilitates research into fat absorption, energy metabolism, and the biochemical effects of dietary fats in clinical and preclinical studies.
• Biochemical Synthesis: Serves as a labeled precursor for the synthesis of more complex isotopically labeled lipids, surfactants, or polymers.
• Quality Control & Reference Standard: Acts as a certified reference material (CRM) for calibrating analytical instruments and ensuring accuracy in fatty acid assays.
