Mercaptosuccinic acid Chemical Properties,Usage,Production
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.
Definition
ChEBI: Thiomalic acid is a C4-dicarboxylic acid. It is functionally related to a succinic acid. It is a conjugate acid of a thiomalate(1-).
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.]
