| | Thiodiglycolic acid Usage And Synthesis |
| Chemical Properties | GREYISH CRYSTALLINE POWDER | | Uses | Detection of copper, lead, mercury, silver: Dubsky et al., C.A. 34, 6185 (1940). | | Uses | It finds it applications in the production of [1,4]oxathiane-2,6-dione by heating. It is employed as an anti-oxidant and reducing agent in cosmetics industry. | | Definition | ChEBI: Thiodiacetic acid is a dicarboxylic acid. | | Safety Profile | Poison by
intraperitoneal route. When heated to
decomposition or on contact with acid or
acid fumes it emits toxic fumes of SOx. See
also MERCAPTOACETIC ACID. | | Purification Methods | Crystallise the acid from water. [Beilstein 3 IV 612.] |
