2-Mercaptobenzoxazole Usage And Synthesis
Chemical Propertiesbeige crystalline powder
Uses2-Mercaptobenzoxazole is used in the surface treatment of materials. It is utilized for protection of metals from corrosion.
Preparation2-Mercaptobenzoxazole has already been described in 1876 by Dunner (Ber. 9, (1876) page 465). 2-Mercaptobenzoxazole and its derivatives are prepared by processes which are based in principle on the reaction between o-aminophenol and alkali metal alkylxanthates. The alkali metal alkylxanthate here can either be employed as such, or it can be produced in the reaction mixture itself from an alkali, a lower alkanol and carbon disulphide.

Application2-Mercaptobenzoxazole is a widely used organic scaffold in medicinal chemistry.
2-Mercaptobenzoxazole and their derivatives are known to posses several biological activities such as antibacterial, antifungal, antiinflammatory, insecticidal and herbicidal. 4-0xo-thiazolidines have also played an important activities as analgesic, anti-HIV, antitubercular, anthelmentic, dye-stuffs, fluorescent and as a photosensitizer. The incorporation of 4-oxothiazolidine and their 5-arylidene moieties in 2-mercaptobenzoxazole frame work has been found to enhance the activity.
DefinitionChEBI: 2-mercapto-1,3-benzoxazole is a benzoxazole.
Reactions2-Mercaptobenzoxazole with ethyl chloroacetate and anhydrous K2C03 in the presence of dry acetone was refluxed on water bath to give ethyl-2-(mercaptobenzoxazolo)acetate.
