Description

L-Lactic Acid-13C3 is a stable isotope-labeled analog of L-lactic acid, where all three carbon atoms are the carbon-13 isotope. This compound is essential for advanced research and analytical applications requiring precise metabolic tracing and quantification. It is primarily utilized by scientists and quality control laboratories in the pharmaceutical, biotechnology, and clinical diagnostics sectors for mass spectrometry, NMR spectroscopy, and metabolic pathway studies.

Application

• Isotope Dilution Mass Spectrometry (IDMS): Serves as an internal standard for the accurate quantification of endogenous lactic acid in complex biological matrices like blood, plasma, and cell culture media.
• Metabolic Flux Analysis (MFA): Used to trace and model carbon flow through central metabolic pathways, such as glycolysis and the TCA cycle, in cellular and microbiological studies.
• Clinical Diagnostics & Biomarker Research: Enables precise measurement of lactate levels for research into conditions like sepsis, metabolic disorders, and cancer metabolism.
• Pharmaceutical Development: Employed in pharmacokinetic and drug metabolism studies to track the fate of drug molecules and their metabolites.
• Nutritional & Sports Science Research: Facilitates studies on energy metabolism, lactate threshold, and muscle fatigue mechanisms.
• Quality Control & Method Validation: Acts as a certified reference material (CRM) for validating analytical methods and ensuring laboratory compliance with standards like ISO 17025.
