|Section2= |Section3= }} Camphorsulfonic acid, sometimes abbreviated CSA or 10-CSA is an organosulfur compound. Like typical sulfonic acids, it is a relatively strong acid that is a colorless solid at room temperature and is soluble in water and a wide variety of organic substances. This compound is commercially available. It can be prepared by sulfonation of camphor with sulfuric acid and acetic anhydride: : In organic synthesis, CSA and its derivatives can be used as resolving agents for chiral amines and other cations.〔André B. Charette "3-Bromocamphor-8-sulfonic Acid" Encyclopedia of Reagents for Organic Synthesis 2001, John Wiley & Sons. 〕 For example, 3-bromocamphor-8-sulfonic acid was used in the synthesis of enantiopure devazepide. *Trimetaphan camsilate (trimethaphan camsylate) is another good example. ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Camphorsulfonic acid」の詳細全文を読む スポンサード リンク
