METLIN: Standards & Technology

The METLIN Metabolite and Chemical Entity Database is the largest repository of experimental tandem mass spectrometry and neutral loss data acquired from standards. The tandem mass spectrometry data on over 960,000 molecular standards (as of October, 2025) is provided to facilitate the identification of chemical entities from tandem mass spectrometry…
