Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, is researched, Molecular C17H19N3O2S, CAS is 73590-85-9, about Design of experiment (DOE) utilization to develop a simple and robust reversed-phase HPLC technique for related substances’ estimation of omeprazole formulations.Application In Synthesis of 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole.
A simple, fast, and sensitive reversed-phase HPLC method with UV detection was developed for the quantitation of omeprazole and its eleven related compounds (impurities) in pharmaceutical formulation using the Thermo Accucore C-18 (50 mm × 4.6 mm, 2.6 μm) column. The separation among all the compounds was achieved with a flow rate of 0.8 mL min-1 employing a gradient program of mobile phase A [0.08 M glycine buffer pH 9.0: acetonitrile; 95:05 (volume/volume)] and mobile phase B [acetonitrile: MeOH; 65:35 (volume/volume)]. The chromatog. detection was carried out at a wavelength of 305 nm. The method was validated for specificity, linearity, and recovery. The huskiness of the method was determined prior to validation using the Design of Experiments (DOE). The ANOVA anal. of DOE with a 95% confidence interval (CI) confirmed the buffer pH of mobile phase A and column temperature as significant Critical Method Parameters (CMPs).
There is still a lot of research devoted to this compound(SMILES：CC1=CN=C(CSC2=NC3=CC(OC)=CC=C3N2)C(C)=C1OC)Application In Synthesis of 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, and with the development of science, more effects of this compound(73590-85-9) can be discovered.
