| Mercaptosuccinic acid Usage And Synthesis |
| Chemical Properties | white to almost white crystalline powder | | Uses | Antirheumatic. | | Uses | Mercaptosuccinic acid is used in the preparation of mercaptosuccinic acid diethyl ester by reaction with ethanol. It is also used as a brightening agent in metal plating. Further, it serves as an intermediate for the synthesis of corrosion inhibitors, soil fumigants, active pharmaceutical ingredients and electroplating agents. | | Uses | Mercaptosuccinic acid has been used as a dopant for the synthesis of carbon nanodots from citric acid. It can be used as a capping and reducing agent to synthesize monolayer-capped gold nanoparticles. | | Brand name | Myochrysine (Merck). | | General Description | Mercaptosuccinic acid(MSA) is a chiral multifunctional intermediate material used as a stabilizing and capping agent in the synthesis of biologically active sulfurs. | | Purification Methods | Dissolve the acid in water and extract it several times with diethyl ether to remove imprities. The aqueous solution gave the acid on freeze-drying. [Beilstein 3 IV 472.] |
