用途: 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]. 物理化学性质: CAS号:74317-53-6 常用中文名:罗丹明B酰肼 常用英文名:Rhodamine B hydrazide 分子式:C28H32N4O2 分子量:456.58 密度:N/A 沸点:N/A 熔点:N/A 闪点:N/A 储存条件:2~8°C |
