Description

Tetracosanoic Acid-1-13C is a stable isotope-labeled analog of lignoceric acid, a key saturated very long-chain fatty acid (VLCFA). This compound is essential for advanced analytical research, providing a critical internal standard for precise quantification and metabolic pathway tracing. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, biotechnology, and life science sectors for mass spectrometry, NMR spectroscopy, and lipidomics studies.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the accurate quantification of lignoceric acid and related VLCFAs in complex biological matrices like plasma, tissues, and cell cultures.
• Metabolic Pathway Tracing: Enables the study of fatty acid elongation, degradation, and incorporation into complex lipids like sphingolipids and ceramides.
• Biomarker Research: Facilitates investigations into diseases associated with VLCFA metabolism, such as adrenoleukodystrophy (ALD) and other peroxisomal disorders.
• Pharmaceutical Development: Supports drug discovery and pharmacokinetic studies where lipid metabolism is a target or a factor.
• Nutritional Science: Used in studies examining the absorption, distribution, and metabolism of dietary saturated fats.
• Quality Control & Reference Material: Serves as a high-purity certified reference standard for calibrating analytical instruments and validating methods.
