5-(2-Methyl-1,3-dioxolan-2-yl)-2-pyridineethanol-d4

5-(2-Methyl-1,3-dioxolan-2-yl)-2-pyridineethanol-d4, also known as (±)-5-(2-Methyl-1,3-dioxolan-2-yl)-2-pyridineethanol-d4 or simply as d4, is a stable isotope-labeled version of the chemical compound 5-(2-Methyl-1,3-dioxolan-2-yl)-2-pyridineethanol (also known as MPDPE). The compound is used as an analytical standard in various fields such as pharmaceutical and biomedical research, as well as in environmental and forensic investigations. The chemical formula of d4 is C11H10D4NO3, and its molecular weight is 218.31 g/mol. The compound is a clear liquid that is soluble in water, methanol, and other polar solvents. It is stable under normal conditions and has a purity of at least 98%. The primary use of d4 is as a reference standard in nuclear magnetic resonance (NMR) spectroscopy, which is a powerful analytical tool used to study the structure and properties of molecules. Specifically, d4 is used as a deuterium-labeled internal standard for the quantification of MPDPE in complex biological matrices. This is important because the presence of endogenous compounds in these matrices can interfere with the accurate detection and quantification of MPDPE. Overall, d4 is a valuable tool for researchers and scientists who require accurate and reliable analytical standards in their work. Its stable isotopic labeling ensures that it can be easily distinguished from other compounds in complex mixtures and provides a precise reference point for the quantification of MPDPE.
