Boix, C.; Ibanez, M.; Sancho, J. V.; Niessen, W. M. A.; Hernandez, F. published the article 《Investigating the presence of omeprazole in waters by liquid chromatography coupled to low and high resolution mass spectrometry: degradation experiments》. Keywords: omeprazole water liquid chromatog mass spectrometry degradation; omeprazole; surface water; time-of-flight mass spectrometry; transformation/degradation products; triple quadrupole mass spectrometry; ultra-high-performance liquid chromatography; urban wastewater.They researched the compound: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole( cas:73590-85-9 ).Recommanded Product: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:73590-85-9) here.
Omeprazole is one of the most consumed pharmaceuticals around the world. However, this compound is scarcely detected in urban wastewater and surface water. The absence of this pharmaceutical in the aquatic ecosystem might be due to its degradation in wastewater treatment plants, as well as in receiving water. Different laboratory-controlled degradation experiments were carried out on surface water to elucidate omeprazole transformation products (TPs). Surface water spiked with omeprazole was subjected to hydrolysis, photo-degradation under both sunlight and UV radiation and chlorination. Analyses by liquid chromatog. coupled to quadrupole time-of-flight mass spectrometry (LC-QTOF MS) permitted identification of ≤17 omeprazole TPs. In a subsequent step, the TPs identified were sought in surface water and urban wastewater by LC-QTOF MS and by LC coupled to tandem mass spectrometry with triple quadrupole. The parent omeprazole was not detected in any of the samples, but 4 TPs were found in several water samples. The most frequently detected compound was OTP 5 (omeprazole sulfide), which might be a reasonable candidate to be included in monitoring programs rather than the parent omeprazole.
