Phthalic acid esters are among the most frequently encountered pollutants in biological extracts. They are very often detected in biological analysis using gas chromatography. Even using high resolution glass capillary columns, the identification of some of these esters remains difficult. In this pa
Positive-ion fast atom bombardment mass spectra of 13 keto acid and keto ester phosphoranes were examined. All compounds gave a protonated molecular ion and characteristic peaks at m/z 303,279,262 and 201. 4 5 6 7 a 9 10 11 12 13 m/z (relative abundance, "h) 477 (41). 403 (54). 377 (58). 347 (45). 3
