  • Reagent and method for detection of carboxylic acids by mass spectrometry
    Patent number: 9045421
    Abstract: Method and reagent for converting a carboxylic acid to a positively charge amide are described. The method and reagent facilitate positive ion mass spectral analysis of carboxylic acids. The method includes reacting a carboxylic acid with a compound having formula I: wherein A and B are aromatic rings, ring A includes a quaternized nitrogen and has n additional ring atoms, each additional ring atom optionally substituted with an RA group, and n is an integer from 4 to 10, and ring B includes a carbon atom and has m additional ring atoms, each additional ring atom optionally substituted with an RB group, and m is an integer from 4 to 10. The compound includes at least one RA or RB group, and the at least one RA and RB group is -L-N(Z)H; and X? is a counterion.
