Description

Ethyl Stearate-D5 is a deuterated analog of ethyl stearate, a fatty acid ester, where five hydrogen atoms are replaced with deuterium. This isotopic labeling is critical for applications requiring precise analytical tracking and internal standards in mass spectrometry. It is an essential reagent for researchers and manufacturers in the pharmaceutical and analytical chemistry sectors who require high-purity, isotopically labeled compounds for method development and quantification.

Application

• Internal standard for the quantitative analysis of fatty acid esters and lipids via Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS).
• Deuterated tracer in metabolic studies and pharmacokinetic research to track absorption, distribution, and metabolism.
• Key starting material or intermediate in the synthesis of more complex deuterium-labeled compounds for research and development.
• Used in nuclear magnetic resonance (NMR) spectroscopy as a solvent or reference compound due to its isotopic purity.
• Component in the formulation of specialty lubricants and plasticizers for research into product performance and degradation.
