Chemical PropertiesDeep red powder
UsesFood Red No. 102 is an artificial coloring food additive. Dye.
Safety ProfileModerately toxic by intraperitoneal route. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx and SOx.
Purification MethodsDissolve the dye in the minimum quantity of boiling water, filter and enough EtOH is added to precipitate ca 80% of the dye. This process is repeated until a solution of the dye in aqueous 20% pyridine has a constant extinction coefficient. [Beilstein 16 I 306.]
