A couple of challenges comes to mind: improving temperature dependence of relative stabilities of polymorphs would help in identifying enantiotropic relationships. 20277-69-4, Name is Sodium methanesulfinate, belongs to thiazines compound, is a common compound. In a pantent, author is Gomha, Sobhi M., once mentioned the new application about 20277-69-4, HPLC of Formula: https://www.ambeed.com/products/20277-69-4.html.
Ethyl 7-Methyl-1-(4-nitrophenyl)-5-phenyl-3-(thiophen-2-yl)-1,5-dihydro-[ 1,2,4]triazolo [4,3-a]pyrimidine-6-carboxylate
A novel compound, ethyl 7-methyl-1-(4-nitrophenyl)-5-phenyl-3-(thiophen-2-yl)-1,5-dihydro[1,2,4] triazolo[4,3-a]pyrimidine-6-carboxylate (7) was synthesized by reaction of N-(4-nitrophenyl) thiophene-2-carbohydrazonoyl chloride (1) with ethyl 6-methyl-4-phenyl-2-thioxo1,2,3,4-tetrahydropyrim idine-5-carboxylate (2). The mechanism of the studied reaction is discussed and the assigned structure was confirmed by elemental analysis and spectral data. Moreover, the in vitro antitumor activities against human lung (A-549) and human hepatocellular carcinoma (HepG-2) cell lines were determined by the MTT method, and the results indicated a high potency compared with the employed standard antitumor drug (Cisplatin).
