Ethyl Stearate-d5 (CAS 1216808-22-8)

Ethyl Stearate-d5, with the CAS number 1216808-22-8, is a deuterium-labeled version of ethyl stearate, an ester formed from stearic acid and ethanol. This molecule has been modified by replacing five hydrogen atoms with deuterium, a heavy isotope of hydrogen, which enhances its chemical stability and resistance to environmental degradation such as oxidation. This alteration is particularly beneficial in analytical research applications where increased molecular stability is required to achieve accurate and reproducible results. Ethyl Stearate-d5 is extensively utilized in studies employing techniques like Nuclear Magnetic Resonance (NMR) spectroscopy and mass spectrometry, where its deuterium atoms provide distinct, sharper signals that greatly improve the clarity and precision of spectral data analysis. This capability is crucial for tracing the metabolic pathways of fatty acid esters and understanding their role in various biological and chemical processes. Additionally, the modification with an ethyl group increases the compound′s solubility in organic solvents, facilitating its application in experiments that examine lipid interactions and behaviors in non-aqueous environments. Researchers leverage Ethyl Stearate-d5 to investigate the dynamics of lipid membranes, the stability of lipid-based formulations, and the interaction of fatty acids with other molecular entities in synthetic and natural settings. This molecule serves as a key tool in advancing the scientific understanding of lipid chemistry and the physical properties of esters in diverse research fields.
