    Product Description

    Rhodamine dithenoyl hydrazide is an N,N-dithenoyl-rhodamine based fluorescent and colorimetric probe for the detection of ferric iron.1 Upon iron binding, rhodamine dithenoyl hydrazide fluoresces and displays excitation/emission maxima of 534/550-700 nm, respectively. It is selective for ferric iron, emitting fluorescence at 588 nm in the presence of ferric iron but not ferrous iron or in a panel of 11 additional cations and 10 anions. Rhodamine dithenoyl hydrazide also exhibits a visual shift from colorless to pink upon addition of ferric iron to aqueous solutions or live cells, which can be detected colorimetrically.

    WARNING This product is not for human or veterinary use.
