23537-25-9 - Reference Information
| biological activity | L-Cysteic acid monohydrate (CAM) is an active endogenous metabolite. |
| use | for organic synthesis. |
| production method | cystine is dissolved in dilute hydrochloric acid, bromine is added dropwise, and the temperature of the reaction solution rises to about 60 ℃. The reaction liquid is evaporated under reduced pressure, the residue is dissolved in distilled water, and the insoluble matter is filtered out. After concentration, the filtrate is cooled and crystallized, filtered, the filter cake is washed with ethanol, and dried to obtain L-sulfoalanine with a yield of 81-90%. |
