Relative retention indexes and linear programmed indexes are given for alkyl-, 4-bromo-, 1-nitro-, <em>C<\/em>-nitro-, and bromonitropyrazoles. Although both N-substituted and N-unsubstituted pyrazoles could be separated on the same columns, 1-nitropyrazoles were sometimes susceptible to denitration at the higher temperatures used. In the experiment, the researchers used many compounds, for example, 3-Methyl-4-nitro-1H-pyrazole (cas: 5334-39-4<a href=\"https:\/\/www.ambeed.com\/products\/5334-39-4.html\">Computed Properties of C4H5N3O2<\/a>).<\/p>\n<p>3-Methyl-4-nitro-1H-pyrazole (cas: 5334-39-4) belongs to pyrazole derivatives.
