摘要:

O-p-Nitrobenzyl-N, N′-diisopropylisourea was shown to react under relatively mild conditions with carboxylic acids to yield thep-nitrobenzyl esters as chromogenic derivatives useful for liquid chromatographic analysis. Thep-nitrobenzyl ester of stearic acid was detectable down to the picomole range.
