Biological Activity:
Rhodamine B hydrazide is a fluorescent derivative based on rhodamine B, containing the spirocyclic structure of Rhodamine B (HY-Y0016), which can be used to detect copper ions (Cu2+), mercury ions, peroxynitrite, hydroxyl radicals and nitric oxide (NO)[1][2][3].
Excitation/emission wavelength:
Conventional detection: 510/578 nm.
Sulfite detection: 554 nm absorption, 574 nm emission (due to the formation of Rhodamine B fluorescent product).
