解説ベンゼンスルホンアミド,C6H7NO2S(157.19).ベンゼンスルホニルクロリドとアンモニアから合成される.無色の針状晶.融点147~148 ℃.熱エタノール,エーテルに易溶,アルカリ性水溶液に可溶,水に難溶.次亜塩素酸ナトリウムと反応させるとN,N-ジクロロベンゼンスルホンアミドC6H5SO2NCl2を生成する.弱酸性(pKa 10.1)で,金属塩にハロゲン化アルキルを作用させるとN-アルキル化される.
用途染料中間体
用途有機合成原料。
使用Biospecific adsorption of carbonic anhydrase to self-assembled monolayers of alkanethiolates that present benzenesulfonamide groups on gold. Biospecific binding of carbonic anhydrase to mixed sams presenting benzenesulfonamide ligands led to a model system for studying lateral steric effects. Benzenesulfonamide modifications at c-7 of ciprofloxacin change its primary target instreptococcus pneumoniae from topoisomerase iv to gyrase. Polar substitutions in the benzenesulfonamide ring of celecoxib afford a potent 1,5-diarylpyrazole class of COX-2 inhibitors.
製造方法Benzenesulfonamide is obtained by amination of benzenesulfonyl chloride.
