Overview
Mass Spectrometry is a powerful analytical technique that is used to determine the molecular weight and generate a fragment ion spectrum of a compound for identification / confirmation using tandem mass spectrometry. This fragmentation pattern, offers a unique molecular signature of organic compounds. Thus MS/MS database with suitable software algorithm /web base search engine can provide an important tool for identification of previously characterized natural products.
The general approaches for most common search are
General Searches:by Name, Formula, CAS Number and Molecular weight.
Mass Spectrometry Based Searches:by MS/MS ion search or product ion search for single compounds,
advanced search and comprehensive search included multiple searches or for Mass spectrometry LC-MS/MS data based search.
