This compound is specifically designed for use as an internal standard or tracer in advanced analytical and metabolic research, providing unmatched precision for quantitative analysis. It is an essential tool for researchers and quality control specialists in the pharmaceutical, nutritional science, and biochemistry sectors who require high-fidelity isotopic labeling for mass spectrometry and NMR studies.

Application

• Internal Standard for Mass Spectrometry (MS): Provides precise quantification of stearate-containing lipids and triglycerides in complex biological matrices.
• Metabolic Pathway Tracing: Used in in vitro and in vivo studies to track the absorption, distribution, metabolism, and excretion (ADME) of fatty acids.
• Pharmaceutical Research: Critical for drug development studies involving lipid-based drug delivery systems and lipid metabolism.
• Nutritional Science: Enables accurate analysis of fat content, digestion, and bioavailability in food and nutritional supplement research.
• Biochemical Research: Serves as a stable isotope-labeled substrate for enzymatic studies related to lipases and lipid metabolism.
• Quality Control & Method Development: Used to validate and calibrate analytical methods (GC-MS, LC-MS) in analytical laboratories.
