Chemical Information Catelog Number: R01-0007 Product Name: BDP 630/650 X NHS ester CAS Number: 2213445-35-1 Molecular Formula: C33H31N4BF2O6S Molecular Weight: 660.5 Purity: NMR 1H, HPLC-MS (95%) Solubility: good in DMF, DMSO Related CAS: 380367-48-6 Product Specification Appearance: dark colored solid ε, L⋅mol-1⋅cm-1: 97000 Fluorescence quantum Yield: 0.91 Excitation Maximum (nm): 628 Emission Maximum (nm): 642BDP 630/650 is a borondipyrromethene fluorophore that has a high molar extinction coefficient, excellent quantum yield, and a relatively long lifetime of the excited state. Due to it, this fluorophore is useful for fluorescence polarization assays that allow to detect binding between molecules. This is an amine reactive NHS ester. It contains an aminohexanoyl linker between the fluorophore and the reactive group.
