Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, improving understanding of environmental issues, and development of new chemical products and materials. 20277-69-4, Name is Sodium methanesulfinate, belongs to thiazines compound, is a common compound. In a pantent, author is Sebbar, Nada Kheira, once mentioned the new application about 20277-69-4, Safety of Sodium methanesulfinate.
Crystal structure of (E)-2-benzylidene-4-[(3-phenyl-4,5-dihydroisoxazol-5-yl)-methyl]-2H-benzo[b][1,4] thiazin-3(4H)-one
In the title compound, C25H20N2O2S, the dihydroisoxazole ring exhibits an envelope conformation with the methine atom being the flap, while the 1,4-thiazine ring displays a screw-boat conformation. The six-membered ring fused to the 1,4-thiazine ring makes dihedral angles of 63.04 (2) and 54.7 (2)degrees with the mean planes through the five-membered heterocycle and the attached phenyl ring, respectively. The phenyl group connected to the 1,4-thiazine ring is disordered over two sites [major component = 0.57 (2)]. The most prominent interactions in the crystal structure are C-H center dot center dot center dot O hydrogen bonds that link molecules, forming inversion dimers, and C-H center dot center dot center dot N hydrogen bonds that link the dimers into columns parallel to the b axis.
