  • Patent number: 7902333
    Abstract: The present invention provides methods for labeling One or two oxygen atom(s) in a carboxyl group of a carboxyl-containing compound with an oxygen isotope selected from oxygen-17 (17O) or oxygen-18 (18O). The methods of the present invention are characterized in that an activated ester of the carboxyl-containing compound (carboxylic acid) is reacted with H217O or H218O in the presence of an activator. In the methods of the present invention, the reaction between the activated ester of a carboxylic acid and H217O or H218O can be allowed to proceed without including drastic conditions such as strongly acidic conditions or alkaline hydrolysis because an activator is used.
