The present invention provides a compound that can utilize hydrogen isotope and, at the same time, can quantify multiplexed samples at one time, as well as decreasing the cost for synthesis of the labeling agent. In addition, the present invention provides a novel method for quantitatively analyzing protein and peptide analytes having different quantities form each other using the labeling agent, wherein y-type fragment ions having a high mass which comprises the analyte remained after coupling the labeling agent with the analyte and then removing a part of the labeling agent through tandem mass spectrometry are utilized to conduct the quantitative analysis.
