Chemical Information Catelog Number: F01-0024 Product Name: BDP TR carboxylic acid CAS Number: 150152-64-0 Molecular Formula: C21H15N2BF2O3S Molecular Weight: 424.23 Purity: NMR 1H, HPLC-MS (95%) Solubility: good in DMF, DMSO Product Specification Appearance: dark colored solid ε, L⋅mol-1⋅cm-1: 69000 Fluorescence quantum Yield: 0.9 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): 589 Emission Maximum (nm): 616BDP TR is a bright and photostable fluorophore for ROX/Texas red channel. It is moderately hydrophobic, has relatively long lifetime of the excited state, and significant two photon cross section. This carboxylic acid derivative can be used for the labeling of alcohols by Steglich esterification, or in non-conjugated form (non-activated carboxy group can be considered inert for applications that do not require conjugation).
