RHODAMINE B - 500%
IUPAC Name: [9-(2-carboxyphenyl)-6-diethylamino-3-xanthenylidene]-diethylammonium chloride
Formula: C28H31ClN2O3
CAS No: 81-88-9
Mol Wt: 479.02
Solubility in water: ~50 g/l
Rhodamine B is often used as a tracer dye within water to determine the rate and direction of flow. Rhodamine dyes fluoresce and can thus be detected easily and inexpensively. Rhodamine dyes are used extensively in biotechnology applications such as fluorescence microscopy, flow cytometry, fluorescence correlation spectroscopy and ELISA.
Rhodamine B is used in biology as a staining fluorescent dye, sometimes in combination with auramine O, as the auramine-rhodamine stain to demonstrate acid fast organisms, notably mycrobaerium.
Rhodamine B is tunable around 610 nm when used as a laser dye. Its luminescence quantum yield is 0.65 in basic ethanol, 0.49 in ethanol 1.0 and 0.68 in 94% ethanol. The fluorescence yield is temperature dependent.Buy Rhodamine / Basic Violet Dye
