Application of 73590-85-9. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, is researched, Molecular C17H19N3O2S, CAS is 73590-85-9, about Going Green in Process Chemistry: Optimizing an Asymmetric Oxidation Reaction To Synthesize the Antiulcer Drug Esomeprazole. Author is McAllister, Graeme D.; Parsons, Andrew F..

Sustainable practices in process chem. are highlighted by a novel, 9 wk team project of 8-12 students, in collaboration with AstraZeneca chemists, in an organic chem. laboratory Students synthesize the antiulcer medicine esomeprazole, which involves the asym. oxidation of pyrmetazole. To provide insight into the modern process chem. industry, they propose environmentally friendly modifications to the asym. oxidation Students first synthesize pyrmetazole and then follow a standard oxidation procedure and carry out modified, greener reactions of their choice. They investigate how a change in reaction conditions affects both the yield and enantioselectivity of esomeprazole. Pos. student feedback was received and student postlab reports were analyzed over a 4 yr period (2015-2018). Results consistently showed that the project provided students with the key tools to develop greener syntheses. This contextual approach not only offers the opportunity to develop valuable communication and team-working skills, but it also gives students creative input into their exptl. work. It teaches the important research skills involved in sustainable process chem., from reproducing and modifying a literature procedure to identifying green metrics.

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.
