A gas chromatographic method is described for the quantitation of some substituted 2-pyrrolidones of biological interest. These compounds are converted to the trimethylsilylated derivatives with N,O-bis(trimethylsilyl)-trifluoroacetamide (BSTFA). The derivatized pyrrolidones are well separated by ga
