Chemical properties of ylidene derivatives of azines. 4. The structure of products resulting from the protonation and transformation of dihydroazinylidenecyanoacetic esters in concentrated sulfuric acid was written by Oleinik, I. V.;Zagulyaeva, O. A.;Denisov, A. Yu.;Mamaev, V. P.. And the article was included in Khimiya Geterotsiklicheskikh Soedinenii in 1990.Recommanded Product: 3-Methoxypyridazine This article mentions the following:
In concentrated H2SO4, azinylidene derivatives I (X = CH, N) have an aromatic structure, whereas several others, e.g., II, retain the ylidene structure. On standing in 95% H2SO4, I are converted to amide esters (III), whereas others are converted to 2-(azinyl)acetamides and amide esters. In the experiment, the researchers used many compounds, for example, 3-Methoxypyridazine (cas: 19064-65-4Recommanded Product: 3-Methoxypyridazine).
3-Methoxypyridazine (cas: 19064-65-4) belongs to pyridazine derivatives. The pyridazine structure is also found within the structure of several drugs such as cefozopran, cadralazine, minaprine, pipofezine, and hydralazine. Pyridazine compounds have attracted interest in various fields like medicinal, industrial, and agricultural research as they are used for numerous biological activities and other applications.Recommanded Product: 3-Methoxypyridazine
