Is it really necessary to acquire accurate-mass fragmentation data? Why isn the accurate mass of the whole compound sufficient to identify it?
This is a very common misconception about accurate-mass. For example, the compound shown here on our website, xemilofiban, has the formula C18H22N4O4. The PubChem database has about 700 compounds with that same formula and exact mass and 938 compounds within 10 ppm of its exact mass (PubChem on 11-21-07).
