In 2022,Kumdale, Prashant Ganpatrao; Shitole, Nana Vikram published an article in Oriental Journal of Chemistry. The title of the article was 《Synthesis of pyrazole compounds by using sonication method》.Safety of Methyl 4-fluorobenzoate The author mentioned the following in the article:
A simple method for the synthesis of pyrazoles derivatives carried out by cyclization of cyanides with hydrazine hydrate by using sonication method. All the prepared compounds were characterized by 1H, 13C NMR and IR spectroscopy. In the experiment, the researchers used many compounds, for example, Methyl 4-fluorobenzoate(cas: 403-33-8Safety of Methyl 4-fluorobenzoate)
Methyl 4-fluorobenzoate(cas: 403-33-8) can be used in the synthesis of trisubstituted imidazole derivatives containing a 4-fluorophenyl group, a pyrimidine ring, and a CN- or CONH2-substituted benzyl moiety.Safety of Methyl 4-fluorobenzoate
