Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 20277-69-4, Name is Sodium methanesulfinate, molecular formula is CH3NaO2S, belongs to thiazines compound, is a common compound. In a patnet, 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.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 20277-69-4. The above is the message from the blog manager. Safety of Sodium methanesulfinate.
