Abstract
We report the use of supercritical fluid chromatography/mass spectrometry (SFC/MS) for numerous applications in drug discovery at Pfizer, La Jolla. Namely, SFC/MS has been heavily relied upon for analysis and purification of a diverse set of compounds from the in-house chemical library. Supporting high-speed SFC/MS quality control of the purified compounds is made possible at high flow rate SFC along with time-of-flight mass detection. The flexibility of SFC/MS systems has been extended with the integration of an atmospheric pressure photoionization source (APPI) for use with more non-polar compounds and enhancements in signal to noise. Further SFC/MS applications of note include chiral analysis for purification and assessment of enantiomers and SFC/MS analysis of difficult to separate hydrophobic peptides.
