Azoles. XIV. Ultraviolet study of pyrazoles was written by Elguero, Jose;Jacquier, Robert;Nguyen Tien Duc Hong Cung. And the article was included in Bulletin de la Societe Chimique de France in 1966.Synthetic Route of C6H9N3O This article mentions the following:
The uv spectra of 170 NH and N-substituted pyrazoles of general structure I were determined at 95° in EtOH. Some of the substituents were Me, CONH2, Ac, p-MeC6H4SO2, Ph, p-BrC6H4, p-O2NC6H4, 2,4-(O2N)2C6H3, and 2,4,6-(O2N)3C6H2. In the 2,4-(O2N)2C6H3 and 2,4,6-(O2N)3C6H2 series a time dependence of spectra is noted. Uv spectra are able to identify pairs of N-substituted pyrazole isomers. In the experiment, the researchers used many compounds, for example, 3,5-Dimethyl-1H-pyrazole-1-carboxamide (cas: 934-48-5Synthetic Route of C6H9N3O).
3,5-Dimethyl-1H-pyrazole-1-carboxamide (cas: 934-48-5) belongs to pyrazole derivatives. As is the case with imidazoles, the pyrazole ring offers many opportunities to create new multiring systems that incorporate this heterocycle. Pyrazoles are commonly used scaffold molecules in drug discovery projects. The use of pyrazole derivatives is based on their analgesic, anti-inflammatory, antipyretic, antiarrhythmic, sedative, muscle relaxant, neuroleptic, anticonvulsant, monoamine oxidase inhibitory, antidiabetic and antibacterial activities.Synthetic Route of C6H9N3O
