| Rhodamine B hydrazide | Rhodamine B hydrazide is a good probe for sulfite, with colorless and non-fluorescent properties. While the emission is related to the concentration of sulfite (5-800 ng/mL; detection limit=1.4 ng/mL (3σ)). Sulfite reduces dissolved oxygen to yield superoxide radicals, which binds to Rhodamine B hydrazide to form Rhodamine B. Rhodamine B hydrazide gives Rhodamine B-like fluorescence in the presence of sulfite, which is enhanced by Tween 80 surfactant micelles. Rhodamine B hydrazide has an absorption maximum at 554 nm and a fluorescence emission maximum at 574 nm [1]. Uses: Scientific research. Group: Fluorescent dye. CAS No. 74317-53-6. Pack Sizes: 10 mM * 1 mL; 5 mg; 10 mg; 25 mg; 50 mg; 100 mg. Product ID: HY-123645. | |
