4-Chloro-3,5-dimethyl-1H-pyrazole (cas: 15953-73-8) belongs to pyrazole derivatives. The strategies for the synthesis of pyrazoles generally can be applied for the construction of indazoles. 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.Reference of 15953-73-8

Metal pyrazolate polymers. Part 3. Synthesis and study of copper(I) and -(II) complexes of 4-Xdmpz (where X = H, Cl, Br, I, and CH3 for Cu(I) and X = H, Cl, Br, and CH3 for Cu(II); dmpz = 3,5-dimethylpyrazolate) was written by Ehlert, Martin K.;Storr, Alan;Thompson, Robert C.. And the article was included in Canadian Journal of Chemistry in 1992.Reference of 15953-73-8 This article mentions the following:

[CuI(4-Xdmpz)]3 (X = H, Cl, Br, I, CH3; Hdmpz = 3,5-dimethylpyrazole) and [CuII(4-Xdmpz)2]n (X = H, Cl, Br, CH3) were synthesized and characterized. Qual. solubility, IR spectroscopic, and DSC studies are reported for all complexes. Mass spectra support trimeric formulations for the copper(I) complexes. Scanning electron micrographs and powder x-ray diffractograms were recorded for the copper(II) compounds Electronic and EPR spectroscopic studies as well as magnetic susceptibility studies from 2 to 300 K are also reported for the copper(II) compounds, which are proposed to have polymeric chain structures. The magnetic data reveal strong antiferromagnetic interactions in all four of the copper(II) compounds The data were analyzed employing an isotropic Heisenberg model for antiferromagnetic coupling in extended chain polymers. Values of the exchange coupling constant, J, are determined as -58, -61, -66, and -66 cm-1 for the X = H, CH3, Cl, and Br complexes resp. The X = Cl compound exhibits an abrupt decrease in magnetic susceptibility below 40 K and possible causes of this anomalous behavior are discussed. In the experiment, the researchers used many compounds, for example, 4-Chloro-3,5-dimethyl-1H-pyrazole (cas: 15953-73-8Reference of 15953-73-8).
