Mercaptosuccinic acid Usage And Synthesis
Chemical Propertieswhite to almost white crystalline powder
UsesMercaptosuccinic 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.
UsesAntirheumatic.
UsesMercaptosuccinic 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.
DefinitionChEBI: 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 nameMyochrysine (Merck).
General DescriptionMercaptosuccinic acid(MSA) is a chiral multifunctional intermediate material used as a stabilizing and capping agent in the synthesis of biologically active sulfurs.
Purification MethodsDissolve 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.]
