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).
