In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called An efficient asymmetric approach to the R-enantiomer impurity of esomeprazole, published in 2016, which mentions a compound: 73590-85-9, mainly applied to esomeprazole preparation enantioselective, HPLC of Formula: 73590-85-9.
The R-enantiomer of esomeprazole (5-methoxy-2-[(4-methoxy-3, 5-dimethyl-2-pyridinylmethyl)sulfinyl]-1H-benzimidazole) was synthesized with high enantioselectivity by asym. oxidation of prochiral sulfide using the oxaziridinium salt. This (R)-enantiomer, useful as a reference for the quality control of esomeprazole was characterized by 1H and 13CNMR, IR and HRMS. The enantiomeric excess was determined by HPLC.
From this literature《An efficient asymmetric approach to the R-enantiomer impurity of esomeprazole》,we know some information about this compound(73590-85-9)HPLC of Formula: 73590-85-9, but this is not all information, there are many literatures related to this compound(73590-85-9).
