Description

Dodecanoic Acid-12-13C is a stable isotope-labeled form of lauric acid, where the carbon atom at the 12th position is the carbon-13 (13C) isotope. This compound is essential as a high-purity internal standard and tracer in advanced analytical chemistry and metabolic research, providing unparalleled accuracy for quantitative analysis. It is primarily required by analytical laboratories, pharmaceutical R&D teams, and academic institutions conducting mass spectrometry (MS), nuclear magnetic resonance (NMR) spectroscopy, and pharmacokinetic studies.

Application

• Internal Standard for Quantitative Analysis: Used in Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS) for the precise quantification of lauric acid and related compounds in complex matrices.
• Metabolic Pathway Tracer: Enables the study of fatty acid metabolism, β-oxidation, and lipid biosynthesis in biological systems for nutritional and pharmaceutical research.
• NMR Spectroscopy: Serves as a valuable probe in 13C NMR studies for structural elucidation and dynamic process analysis due to its specific isotopic labeling.
• Pharmaceutical Development: Employed in drug metabolism and pharmacokinetics (DMPK) studies to track the absorption, distribution, metabolism, and excretion (ADME) of lipid-based drug formulations.
• Quality Control & Method Validation: Critical for developing and validating robust analytical methods in compliance with Good Laboratory Practice (GLP) and ICH guidelines.
• Biochemical Research: Facilitates investigations into lipidomics, membrane biology, and the role of medium-chain fatty acids in cellular processes.
