Rhodamine 6G
Forms
Rhodamine 6G usually comes in three different forms. Rhodamine 6G chloride is a bronze/red powder with the chemical formula C28H31ClN2O3. Although highly soluble, this formulation is very corrosive to all metals except stainless steel. Other formulations are less soluble, but also less corrosive. Rhodamine 6G perchlorate (C28H31ClN2O7) comes in the form of red crystals, while rhodamine 6G tetrafluoroborate (C28H31BF4N2O3) appears as maroon crystals.[1]
