Ethyl acetoacetate-d5（Cat No.:I041439）is a deuterated form of ethyl acetoacetate, in which five hydrogen atoms are replaced by deuterium. This isotopic substitution provides a useful tool for researchers, especially in nuclear magnetic resonance (NMR) spectroscopy, as it helps in studying reaction mechanisms, chemical structures, and molecular dynamics without influencing the compound’s reactivity. The compound is widely used in both synthetic chemistry and analytical research. Its stable isotope labeling makes it an ideal candidate for use as an internal standard in mass spectrometry, enhancing the accuracy and reliability of quantitative analysis.
