In the experiment, the researchers used many compounds, for example, 1-Ethyl-1H-pyrazol-5-amine (cas: 3528-58-3<a href=\"https:\/\/www.ambeed.com\/products\/3528-58-3.html\">HPLC of Formula: 3528-58-3<\/a>).<\/p>\n<p>1-Ethyl-1H-pyrazol-5-amine (cas: 3528-58-3) belongs to pyrazole derivatives.

There are a number of antimicrobial compounds containing pyrazole moiety as the core unit.
