In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Design, synthesis and antimycobacterial activity of novel nitrobenzamide derivatives, published in 2019-02-28, which mentions a compound: 3939-12-6, Name is 6-Fluoronicotinonitrile, Molecular C6H3FN2, SDS of cas: 3939-12-6.
A series of nitrobenzamide derivatives containing N-benzyl or N-pyridinylmethyl moieties I [R = H, 5-CF3, 5-F, etc.; R1 = F, 4-chloro-1-piperidyl, 4-(4-fluorophenyl)piperazin-1-yl, etc.; X = Y = CH; X = CH, Y = N; X = N, Y = CH] was designed and synthesized as new anti-tubercular agents. Many of synthesized compounds I exhibited potent in vitro antitubercular activity. Four compounds I [R = 5-NO2; R1 = 4-MeO, 4-(trifluoromethyl)-1-piperidyl, 4-chloro-1-piperidyl, 4-(4-fluorophenyl)piperazin-1-yl] had not only the same excellent MIC values against both drug-sensitive MTB strain H37Rv and two drug-resistant clin. isolates as PBTZ169 and the lead I [R = 5-NO2; R1 = 4-(trifluoromethyl)-1-piperidyl; X = Y = CH], but also acceptable safety indexes.
The article 《Design, synthesis and antimycobacterial activity of novel nitrobenzamide derivatives》 also mentions many details about this compound(3939-12-6)SDS of cas: 3939-12-6, you can pay attention to it, because details determine success or failure
