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.
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).
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.
