4-Fluoro-N,N-dimethylbenzenesulfonamide (cas: 383-31-3) belongs to amides. Amides can be viewed as a derivative of a carboxylic acid RC(=O)OH with the hydroxyl group –OH replaced by an amine group −NR′R″; or, equivalently, an acyl (alkanoyl) group RC(=O)− joined to an amine group. Amides are stable compounds. The lower-melting members (such as acetamide) can be readily purified by fractional distillation. Most amides are solids which have low solubilities in water.HPLC of Formula: 383-31-3

C(sp2)-H Borylation of fluorinated arenes using an air-stable cobalt precatalyst: electronically enhanced site selectivity enables synthetic opportunities was written by Obligacion, Jennifer V.;Bezdek, Mate J.;Chirik, Paul J.. And the article was included in Journal of the American Chemical Society in 2017.HPLC of Formula: 383-31-3 This article mentions the following:

Cobalt(II) carboxylate complexes with pincer pyridinediphosphine tridentate ligands (RPNP) catalyze ortho-directed C-H-borylation of aryl fluorides with electronically enhanced site selectivity, as evidenced by the high ortho-to-fluorine selectivity observed in the C(sp2)-H borylation of fluorinated arenes. Both the air-sensitive cobalt(III) dihydride boryl [[4-Me-2,6-(iPr2PCH2)2py]CoH2BPin] (1) and the air-stable cobalt(II) bis(pivalate) [[4-Me-2,6-(iPr2PCH2)2py]Co(O2CtBu)2] (2) compounds were effective and exhibited broad functional group tolerance across a wide range of fluoroarenes containing electronically diverse functional groups, regardless of the substitution pattern on the arene. The electronically enhanced ortho-to-fluorine selectivity observed with the cobalt catalysts was maintained in the presence of a benzylic dimethylamine and hydrosilanes, overriding the established directing-group effects observed with precious-metal catalysts. The synthetically useful selectivity observed with cobalt was applied to an efficient synthesis of the anti-inflammatory drug flurbiprofen. In the experiment, the researchers used many compounds, for example, 4-Fluoro-N,N-dimethylbenzenesulfonamide (cas: 383-31-3HPLC of Formula: 383-31-3).
