I found the field of Chemistry very interesting. Saw the article Synthesis of novel 8-nitro-substituted 1,3-benzothiazin-4-ones published in 2020. COA of Formula: C7H4F2O2, Reprint Addresses Nosova, EV (corresponding author), Ural Fed Univ, Inst Chem Engn, Ekaterinburg 620002, Russia.; Nosova, EV (corresponding author), Russian Acad Sci, I Ya Postovsky Inst Organ Synth, Ural Branch, Ekaterinburg 620990, Russia.. The CAS is 385-00-2. Through research, I have a further understanding and discovery of 2,6-Difluorobenzoic acid
New 2,5-bis(azacyclohex-1-yl)-8-nitro-1,3-benzothiazin-4-ones were synthesized from 2,6-difluorobenzoic acid in two preparative stages. The ethoxycarbonylpiperazino derivative surpasses in tuberculostatic activity (MIC 4 mu g ml(-1)) its 5-fluoro-8-H-counterpart. The first representative of 5-fluoro-8-nitro-1,3-benzothiazin-4-ones was obtained through the condensation of 2,6-difluoro-3-nitrobenzoyl isothiocyanate and N-methylindole.
About 2,6-Difluorobenzoic acid, If you have any questions, you can contact Nosova, EV; Batanova, OA; Lipunova, GN; Charushin, VN or concate me.. COA of Formula: C7H4F2O2
