Chang, Kuei-Choo; Grimmett, M. Ross; Ward, David D.; Weavers, Rex T. published the artcile< The nitration of brominated pyrazoles in aqueous sulfuric acid>, HPLC of Formula: 13808-65-6, the main research area is bromopyrazole nitration substituent; pyrazole bromo nitration substituent.
Nitration in 80% H2SO4 of 4-bromopyrazoles gives rise to considerable nitrodebromination. Compounds with no alkyl or aryl substituent on N give only the 4-nitro products, except 4-bromo-3-phenylpyrazole which gives the p-nitrophenyl compound N-Alkyl-4-bromopyrazoles give products of nitrodebromination as well as those arising from nitration in the 3- and/or 5-positions. N-Aryl-4-bromopyrazoles can also undergo nitration of the aryl substituent.
Australian Journal of Chemistry published new progress about Nitration. 13808-65-6 belongs to class pyrazoles-derivatives, and the molecular formula is C9H7BrN2, HPLC of Formula: 13808-65-6.
