|Section2= |Section6= |Section7= }} Cysteamine is the chemical compound with the formula HSCH2CH2NH2. It is the simplest stable aminothiol and a degradation product of the amino acid cysteine. It is often used as the hydrochloride salt, HSCH2CH2NH3Cl. The comparatively high melting point of cysteamine (95-97 °C), indicates that it exists in a salt form. ==Preparation== It can also be prepared by the reaction of ethylenimine with hydrogen sulfide.〔 :(NHCH2CH2) + H2S → HSCH2CH2NH2 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「Cysteamine」の詳細全文を読む スポンサード リンク
