Spectra were plotted, and absorption maximum and mol. extinction coefficients were tabulated. Substituents were Me, CO2R, Et, NH2, and NO2. Changes in spectra, mol. refraction, and basicities for pyrazole and Me derivatives confirmed a hyperconjugation effect for Me in 5- and 3-positions. Pyrazolecarboxylic acids and esters showed conjugation of CO with ring. The 208 m\u03bc band was associated with the chromophore C:CCO2H. The 200-210 m\u03bc band in pyrazole was assigned to the first excited level, antisymmetric combination, type B1. N-Phenylpyrazole showed conjugation between rings or between ring and imine, depending on substitution position, while 5-Me and 2-Me compounds were sterically hindered. Nitration in position 4 or 4&#8242; caused conjugation of NO2 with imine.Methyl 1H-pyrazole-3-carboxylate(cas: 15366-34-4<a href=\"https:\/\/www.ambeed.com\/products\/15366-34-4.html\">Quality Control of Methyl 1H-pyrazole-3-carboxylate<\/a>) was used in this study.<\/p>\n<p>Methyl 1H-pyrazole-3-carboxylate(cas: 15366-34-4) belongs to pyrazoles.
