PR81:1-Rhodamine 6G
Pigment Name
PR81:1-Rhodamine 6G
Pigment Type
organic, fluorone dye
Chemical Formula
C28H31N2O3Cl
Properties
Rhodamine 6G is a staining reddish-yellow pigment that has fluorescent properties. It is extremely soluble in both water and alcohol. Fluorescent molecules absorb light at one wavelength and emit light at a longer wavelength.
Permanence
Rhodamine 6G, like all fluorescent dyes, is not considered permanent, however it is reported to have high stability for a fluorone dye.
Toxicity
Rhodamine 6G is toxic, however it can be biologically inactive and hence non-toxic in a lake pigment form.
History
Rhodamine dyes are often used for microscopy in the biological sciences.
