Pawelczyk, Ewaryst; Wachowiak, Roman published an article about the compound: Sodium 4-butyl-3,5-dioxo-1,2-diphenylpyrazolidin-4-ide( cas:129-18-0,SMILESS:O=C(N(C1=CC=CC=C1)N2C3=CC=CC=C3)[C-](CCCC)C2=O.[Na+] ).Quality Control of Sodium 4-butyl-3,5-dioxo-1,2-diphenylpyrazolidin-4-ide. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:129-18-0) through the article.
The decomposition products formed when 20% aqueous alk. solutions of phenylbutazone Na salt were aged in sunlight were isolated and identified. The colored decomposition products were isolated by CHCl3 extraction; the colorless products were extracted with ether from the acidified solution The extracts were concentrated and separated by thin-layer chromatog. The 5 decomposition products isolated and identified with Ce(SO4)2 were (Rfvalue given) 4-hydroxyphenylbutazone (0.33), N-(2-carboxycaproyl)-hydrazobenzene (0.1), N-(2-carboxy-2-hydroxycaproyl)hydrazobenzene (0.55), trans-azobenzene (0.78), and cis-azobenzene (0.62).
