标题 :Trifluoroborate mass spectrometric tags
发明人：HUANG YUMEI
权利人:CELLMOSAIC INC
摘要:The invention provides compositions and methods for mass spectrometric (MS), organic synthesis, and applications of organo-trifluoroborate, for example, as mass tags for use in negative ion mode. When subject to MS fragmentation, organo-trifluoroborates preferentially undergo neutral losses of hydrogen fluoride (HF) or boron trifluoride (BF 3 ) molecules, transferring the negative charge to the rest of the molecule. Such a fragmentation pattern is used to detect and quantitate analytes of interest after derivatization with organo-trifluoroborates.
