Ethyl methanesulfonate-d5 (Cat No.:M125825) is a stable isotopic labeled compound commonly used in scientific research, particularly in studies of mutagenesis and DNA damage. The “d5” denotes the presence of five deuterium atoms, which replace the regular hydrogen atoms, making it useful in mass spectrometry and other analytical techniques to trace and quantify chemical reactions. EMS itself is an alkylating agent, known for its ability to introduce mutations by transferring an ethyl group to DNA, leading to genetic changes. EMS-d5 allows precise tracking of these processes in experimental settings.
