CAS: 1869-24-5|2- (Trifluoromethyl) benzenesulfonamide

2-(Trifluoromethyl)benzenesulfonamide (CAS 1869-24-}5) yog fluorine- muaj cov organic compound nrog cov qauv tshuaj ntawm C₇H₆F₃NO₂S thiab qhov hnyav ntawm 225.19. Cov hauv qab no yog kev sib koom ua ke ntawm nws cov ntaub ntawv tseem ceeb: 2-(Trifluoromethyl) benzenesulfonamide zoo nkaus li cov hmoov dawb rau lub teeb daj crystalline hmoov, nrog lub melting point ntawm 120-122℃thiab qhov ceev ntawm 1.47 g / cm³. Nws yog yooj yim soluble nyob rau hauv polar organic solvents xws li methanol, ethanol, thiab acetone, thiab me ntsis soluble nyob rau hauv dej. Nws cov qauv molecular muaj ib lub nplhaib benzene, ib pawg trifluoromethyl (-CF₃) thiab sulfonamide pawg (-SO₂NH₂), uas pab pawg sulfonamide yog acidic thiab tuaj yeem koom nrog cov tshuaj tiv thaiv acid.

• Pharmaceutical intermediates:2-(Trifluoromethyl) benzenesulfonamide yog ib qho tseem ceeb nruab nrab siv nyob rau hauv lub synthesis ntawm anti-androgen tshuaj Casodex thiab herbicide penoxsulam, piv txwv li, nws yog siv los tsim imidazopyridine tebchaw los ntawm oxidative sulfonamide methylation (xws li Zhao li al., 2).
• Cov tshuaj tiv thaiv catalytic:Nws koom nrog ester synthesis, aldehyde condensation thiab lwm yam kev cuam tshuam raws li acidic catalyst, piv txwv li, nyob rau hauv esterification cov tshuaj tiv thaiv ntawm acetic acid thiab ethanol, CO₂-induced theem sib cais yog siv los txhim kho tus nqi hloov dua siab tshiab.

• 2-(Trifluoromethyl) benzenesulfonamide yuav tsum tau muab cia kom deb ntawm qhov hluav taws kub thiab cua sov thiab tuav hauv qhov chaw uas muaj cua zoo.
• Thaum siv lossis tuav, yuav tsum hnav hnab looj tes tiv thaiv, tsom iav thiab khaub ncaws tiv thaiv tsim nyog.
• Nws yuav tsum tau muab cia rau hauv qhov chaw qhuav, txias, qhov cua kom deb ntawm lwm cov tshuaj thiab cov khoom siv hluav taws xob.
