Chemical Information Catelog Number: R01-0010 Product Name: BDP R6G NHS ester CAS Number: 335193-70-9 Molecular Formula: C22H18BF2N3O4 Molecular Weight: 437.21 Purity: NMR 1H, HPLC-MS (95%) Solubility: good in DMF, DMSO, DCM Related CAS: 1393363-07-9 (chloride) Product Specification Appearance: dark-green crystals Fluorescence quantum Yield: 0.96 Excitation Maximum (nm): 530 Emission Maximum (nm): 548BDP R6G NHS ester is an amine-reactive borondipyrromethene dye (an analog of BODIPY® R6G NHS ester) that has absorption and emission spectra similar to R6G. BDP R6G is a bright and photostable dye that exhibits long living fluorescence that has little pH dependence. Due to the long fluorescence lifetime, this dye is useful for fluorescence polarization assays, and for two-photon experiments.
