Solvatochromism of Heteroaromatic Compounds: XIX. Factors Affecting Quantitative Characteristics of Solvatochromism in Aprotic Inert Media was written by Turchaninov, V. K.;Vokin, A. I.;Aksamentova, T. N.;Krivoruchka, I. G.;Shulunova, A. M.;Andriyankova, L. V.. And the article was included in Russian Journal of General Chemistry (Translation of Zhurnal Obshchei Khimii) in 2003.COA of Formula: C4H5N3O2 This article mentions the following:
The effects of aprotic inert media on the electronic absorption spectra of aromatic nitro compounds p-NO2C6H4R were used as evidence for the linear correlation between the slope sa of the solvatochromism equations νmax = ν0 + saπ* and the dipole moments of the mols. in their ground electronic state μg. A linear correlation was established between ν0 and the first ionization potential of subunits PhR. A new approach to estimating the dipole moment of electronically excited mols. (μe) for mols. like p-NO2C6H4R from the correlation μe = rμg was proposed. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-nitro-1H-pyrazole (cas: 54210-32-1COA of Formula: C4H5N3O2).
1-Methyl-3-nitro-1H-pyrazole (cas: 54210-32-1) belongs to pyrazole derivatives. Pyrazoles, a five-membered heterocycle containing two adjacent nitrogen atoms, are the core structures found in a number of molecules that possess a wide range of pharmaceutical and agricultural activities. Pyrazole the presence of this nucleus in pharmacological agents of diverse therapeutic categories such as celecoxib, a potent anti-inflammatory, the antidepressant agent fezolamide have proved the pharmacological potential of the pyrazole moiety.
