MZanswers
tools for high resolution mass spectrometry
Search for a known compound
Any organic compound analyzed in a mass spectrometer is likely to be recorded in the PubChem substance database.
The MZanswers search tool interrogates the database for formulas matching the detected mass/charge of a ion,
within an allowed mass range.
The resulting formulas are ranked by a score and each formula is
linked to matching PubChem substances, with details of structures and common names.
