New Advances in Chemical Research in 2021. Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis,and research on the structure and performance of functional materials. 824-79-3, Name is Sodium 4-methylbenzenesulfinate, molecular formula is C7H7NaO2S, belongs to isothiazole compound. In a document, author is Orlando, Ahmed M., introduce the new discover, Quality Control of Sodium 4-methylbenzenesulfinate.
A new monoclinic form of the title compound, C14H17N3O3S, has been found upon slow crystallization from water. Another monoclinic form of the compound was obtained previously from a mixture of dichloromethane and diethyl ether [Clerici et al. (2002). Tetrahedron, 58, 5173-5178]. Both phases crystallize in space group P2(1)/n with one molecule in the asymmetric unit. The formally single exocyclic C-N bond that connects the -NEt2 unit with the thiazete ring is considerably shorter than the adjacent, formally double, endocyclic C=N bond. This is likely to be due to the extended conjugated system between the electron-donor diethylammine fragment and the electron-withdrawing sulfonyl group. In the newly discovered polymorph, the methoxy group is rotated by almost 180 degrees around the phenyl-OCH3 bond, resulting in a different molecular conformation.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield. If you are hungry for even more, make sure to check my other article about 824-79-3, Quality Control of Sodium 4-methylbenzenesulfinate.
