Chemical Information Catelog Number: F01-0016 Product Name: BDP R6G carboxylic acid CAS Number: 174881-57-3 Molecular Formula: C18H15BF2N2O2 Molecular Weight: 340.13 Purity: NMR 1H, HPLC-MS (95%) Solubility: good in DMF, DMSO, ethanol, methanol, DCM Product Specification Appearance: colorless solid ε, L⋅mol-1⋅cm-1: 70,000 Fluorescence quantum Yield: 0.96 Storage Conditions: 24 months after receival at -20°C in the dark. Transportation: at room temperature for up to 3 weeks. Avoid prolonged exposure to light. Desiccate. Excitation Maximum (nm): 530 Emission Maximum (nm): 548BDP R6G is a borondipyrromethene dye, an analog of BODIPY® R6G. The fluorophore has absorption and emission spectra resembling R6G rhodamine. The carboxylic acid can be used in experiments when conjugation of the dye to other molecules is not necessary. The carboxylic acid group can also be activated for subsequent labeling reactions like Steglich esterification.
