In the experiment, the researchers used many compounds, for example, 4-Chloro-3,5-dimethyl-1H-pyrazole (cas: 15953-73-8<a href=\"https:\/\/www.ambeed.com\/products\/15953-73-8.html\">Electric Literature of C5H7ClN2<\/a>).<\/p>\n<p>4-Chloro-3,5-dimethyl-1H-pyrazole (cas: 15953-73-8) belongs to pyrazole derivatives.

Protonation of pyrazole in strong acid leads to pyrazolium cations, which undergo electrophilic substitution preferentially at C3 rather than C4.
