Provided herein is synthesis of novel mass spectrometry-cleavable cross-linking agents. The novel mass spectrometry-cleavable cross-linking agents can be used in mass spectrometry, tandem mass spectrometry, and multi-stage tandem mass spectrometry to facilitate structural analysis of intra-protein interactions in proteins and inter-protein interactions in protein complexes. Also provided are methods of mapping intra-protein interactions in proteins and inter-protein interactions in protein complexes.
