While the job of a research scientist varies, Name: Tetrazolium Red, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards.298-96-4, Name is Tetrazolium Red, SMILES is [N+]1(C2=CC=CC=C2)=NC(C3=CC=CC=C3)=NN1C4=CC=CC=C4.[Cl-], belongs to naphthyridine compound. In a article, author is Chaitanya, M. V. S. R. K., introduce new discover of the category.
The reaction of 2-aminopyridine (1) with ethoxymethylenemalonic ester gave 4-ethoxy-3-oxo-2-(pyridine-2-yl aminomethylene)-butyric acid ethyl ester (2) which on cyclization in the presence of hot PPA gave 4-oxo-1,4-dihydro-[1,8] naphthyridine-3-carboxylic acid ethyl ester (3). The latter on reaction with hydrazine hydrate resulted in, 4-oxo-1,4-dihydro-[1,8] naphthyridine-3-carboxylic acid hydrazide (4). The reaction of 4 in acetic acid with benzaldehydes yielded 3-(5-phenyl-[1,3,4] oxadiazol-2-yl)-1H-[1,8] naphthyridin-4-ones (5). In another reaction, 4 on treatment with acetylacetone gave 3-(3,5-dimethyl-pyrazole-1-carbonyl)-1H-[1,8] naphthyridin-4-ones (6). The hydrazide 4 was further cyclized with carbon disulphide in the presence of potassium hydroxide followed by acidification to get 3-(5-mercapto-[1,3,4] thiadiazol-2-yl)-1H-[1,8] naphthyridin-4-ones (7).
In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model and predict the effects of solvation within porous materials, I hope to 298-96-4 help many people in the next few years. Name: Tetrazolium Red.
