DL-METHIONINE (3,3,4,4-D4) is a deuterium-labeled methionine amino acid in the DL (racemic) form, featuring the thioether-containing side chain characteristic of methionine and a backbone bearing both an amino group and a carboxyl group. The molecule incorporates four deuterium atoms at the 3,3,4,4 positions of the methionine carbon framework, while retaining the free amino and carboxyl functionalities that define it as an unprotected amino acid suitable for salt formation or derivatization. As an isotopically labeled tracer, it is used in analytical method development and quantitative studies such as isotopic tracing, mass spectrometry-based analysis, and structure-property or reaction-pathway investigations where methionine-specific labeling is required.
