2',4',5',7'-TETRABROMO-3,4,5,6-TETRACHLOROFLUORESCEIN Usage And Synthesis

Description

Solvent Red 48 is classed chemically as a fluoran color. It conforms to the formula. (To identify the colorant allowed for use in the European Union (EU), the INCI Name CI 45410 must be used, except for hair dye products).

Preparation

will Resorcinol and 4,5,6,7-Tetrachloroisobenzofuran-1,3-dione condensation,The resulting 4,5,6,7 – tetrachloro-fluorescein tetrabromide, then made into the free acid form.

Definition

ChEBI: Phloxine O is a xanthene dye that is fluorescein in which the hydrogens at positions 2',4',5' and 7' are replaced by bromo groups, and the hydrogens at positions 4,5,6 and 7 are replaced by chloro groups. It is a red synthetic pigment which is widely used in colored cosmetics (e.g. lipsticks and blushers). It has a role as a fluorescent dye. It is a xanthene dye, a member of 2-benzofurans, a gamma-lactone, an organic heteropentacyclic compound, a polyphenol, an oxaspiro compound, a dibromobenzene and a tetrachlorobenzene. It is functionally related to a fluorescein (lactone form).

Flammability and Explosibility

Not classified

Properties and Applications

brilliant blue light red. Soluble in water for blue light red, with weaker SAP green fluorescence, soluble in ethanol for blue light red, with a brick red fluorescence. In concentrated sulfuric acid to yellow, dilution after yellow red precipitation. Mainly used for hydrocarbon solvent, oil, lipid, paraffin wax, petroleum products, varnish, plastic coloring.
