Is rhodamine B soluble?
Rhodamine B base is also used as a laser dye, tunable around 610 nm with the fluorescence yield being temperature dependent. Solubility : Soluble in ethanol (1 mg/ml), methanol, chloroform, and DMF. Insoluble in water.
How do you dissolve rhodamine B?
Dissolve 0.1 g of sample of rhodamine B in 100 mL of water. Not more than a faint trace of turbidity or insoluble matter should remain. Dissolve 0.1 g of sample in alcohol.
Is rhodamine B hydrophilic or hydrophobic?
Fluorescent dye Rhodamine B was used as a model hydrophilic drug in controlled release experiments after it was encapsulated in solution-blown soy-protein-containing hydrophilic nanofibers as well as in electrospun hydrophobic poly(ethylene terephthalate) (PET)-containing nanofibers.

Is rhodamine B an acid or base?
Rhodamine B base is a colorless dye with undetectable fluorescence feature. In acidic condition, rhodamine B base gets transformed into a colored rhodamine dye that acts as a stable and efficient laser dye.
What is the pH of rhodamine B?
The fluorescence of rhodamine B can be strongly affected by its environmental pH value. By directly introducing the dye into various glycine solution, the fluorescence was used to monitor the pH value in the range of 5.9 ~ 6.7.
Why is rhodamine B fluorescent?
General description. Rhodamine B is bright-red in color. Rhodamine B is a xanthene dye, which functions as a water tracer fluorescent. It is used as a staining fluorescent dye.
How do you make rhodamine B?
Stock Standard 1 Dissolve 0.01 g of rhodamine B standard in 10 mL of DI water. The concentration of Stock Standard 1 will be 1000 μg/mL. Stock Standard 2 Dilute 200 μL of Stock Standard 1 to 10 mL with DI water.
What is rhodamine B used for?
As one of the most commonly used dyes, Rhodamine B (RhB) is widely used in industrial purposes, such as printing and dyeing in textile, paper, paints, leathers etc. However, the organic dyes will cause serious environmental and biological problems, even capable to induce irritation to the skin, eyes.
