their unique features and diverse biological functions. Achieving rapid separation and accurate quantification, however, remains a challenge because of their low abundance and the co-existence of numerous structural isomers. In this study, we developed a novel approach using isotopechemical labeling for ultrasensitive determination of di/tripeptides in biologicalsamples. We successfully synthesized a
