The Wiley Registry of Tandem Mass Spectral Data, MSforID is a database of tandem mass spectra allowing the identification of small molecules.

Due to the combination of a unique search algorithm and an advanced database structure, “MSforID” allows sensitive and specific identification of small molecules irrespective of the instrument used to generate the data.

Library entries were generated on a high-resolution instrument with electrospray ionization in positive and negative ion mode.
