Description

7,7,8,8-Tetradeuteriodocosanoic Acid is a deuterium-labeled derivative of behenic acid, a long-chain saturated fatty acid. This stable isotope-labeled compound is essential for advanced analytical research, providing a non-radioactive tracer with distinct mass spectral properties. It is primarily utilized by researchers and scientists in pharmaceutical development, metabolic studies, and lipid biochemistry who require precise internal standards for mass spectrometry.

Application

• Mass Spectrometry Internal Standard: Serves as a critical quantitative reference standard in GC-MS and LC-MS analyses for behenic acid and related lipids.
• Metabolic Pathway Tracing: Used in deuterium labeling studies to investigate fatty acid metabolism, absorption, and β-oxidation in biological systems.
• Pharmaceutical Research: Employed in the development and validation of analytical methods for lipid-based drug formulations and pharmacokinetic studies.
• Biochemical Research: Acts as a probe in enzymatic studies involving fatty acid synthesis, elongation, or degradation pathways.
• Nutritional Science: Facilitates the accurate quantification of behenic acid in complex matrices like food products, oils, and biological fluids.
• Stable Isotope Labeling: Provides a building block for synthesizing more complex deuterium-labeled compounds for specialized research applications.
