    Disclosed are linear discrete PEG constructs, which can be created and produced in a precise and reproducible way. Key to being able to do these things, where x in the discrete PEGX can vary from about 2 to about 64, is that the processes used to make each linear portion is controlled to give essentially one oligomer/one compound. Having a variable length linear discrete PEG construct that is (a) primarily an linear discrete PEG construct with diagnostic or therapeutic groups attached along a chain of attachment cores, which is attached to a preferential locator; (b) is an m-discrete PEG as the terminal construct on the linear portion, and "hidden"; (c) or linear discrete PEG with a terminus group that can be either negatively or positively charged, or neutral; and any of the discrete PEG portions can be designed to be cleaved after entering the cell.

    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.
