Description

Octadecanoic-2,2-D2 Acid is a deuterium-labeled derivative of stearic acid, a saturated long-chain fatty acid. This isotopically labeled compound is essential for advanced research and analytical applications where precise molecular tracking and quantification are required. It is primarily utilized by scientists and manufacturers in the pharmaceutical, biochemical, and material science industries for use as an internal standard, tracer, or building block in synthesis.

Application

• Analytical Chemistry Internal Standard: Used in mass spectrometry (MS), gas chromatography (GC), and liquid chromatography (LC) for the accurate quantification of stearic acid and related compounds in complex matrices.
• Metabolic Pathway Tracing: Serves as a stable isotope tracer in biochemical and nutritional studies to investigate lipid metabolism, absorption, and conversion in biological systems.
• Pharmaceutical Research: Employed in the development and testing of new drug compounds, particularly in pharmacokinetic studies to monitor drug-lipid interactions.
• Material Science Research: Acts as a labeled precursor in the synthesis of specialized surfactants, lubricants, or polymers to study their structure, properties, and degradation.
• Deuterated Standard Production: Used as a starting material or reference compound for synthesizing other deuterium-labeled molecules for research and diagnostic purposes.
