Boleda, M. Rosa published the artcileSurvey of the occurrence of pharmaceuticals in Spanish finished drinking waters, Recommanded Product: Diatrizoic Acid, the main research area is pharmaceutical tandem mass spectrometry finished drinking water pollution Spain.
Fifty samples of finished drinking waters (FDWs) from Spain covering 12 million inhabitants were tested for 53 pharmaceuticals pertaining to 12 different Anatomical Therapeutic Chem. (ATC) classification system codes. The studied compounds are a combination of most commonly consumed pharmaceuticals with other barely reported in the literature. Five compounds, azithromycin, clarithromycin, erythromycin, sulfamethoxazole, and ibuprofen were tentatively identified by liquid chromatog. coupled to tandem mass spectrometry (LC-MS/MS) in some samples (2 to 15 %), but only ibuprofen and azithromycin could be confirmed when analyzed by liquid chromatog.-high-resolution mass spectrometry (LC-HRMS) with a quadrupole-Orbitrap instrument. Concentration levels of ibuprofen in the pos. samples ranged from 12 to 17 ng/L (n = 6) while for azithromycin values from 5 to 9.5 ng/L (n = 3) were found. Ibuprofen fragmentation behavior in different mass spectrometry instrument configurations (triple quadrupole, quadrupole-ion trap, and quadrupole-Orbitrap) was evaluated.
Environmental Science and Pollution Research published new progress about Analgesics. 117-96-4 belongs to class isoquinoline, name is Diatrizoic Acid, and the molecular formula is C11H9I3N2O4, Recommanded Product: Diatrizoic Acid.
