Chemical Information Catelog Number: F01-0237 Product Name: BDP FL-PEG5-acid CAS Number: 2093197-98-7 Molecular Formula: C27H40BF2N3O8 Molecular Weight: 583.4 Purity: 98% Solubility: DMSO, DMF, DCM, low solubility in water Product Specification Excitation Maximum (nm): 503 ε, L⋅mol−1⋅cm−1: 80,000 Emission Maximum (nm): 509 Package: 1 mg/2 mg/5 mg Storage Condition: -20 °CBDP FL-PEG5-acid is a BDP FL acid linker containing a hydrophilic PEG spacer arm. BDP FL is a green-fluorescent dye and the hydrophilic PEG spacer arm increases water solubility as well as membrane permability. BDP FL dye has several characteristics that make it potentially superior in some applications, including high extinction coefficient, high fluorescence quantum yield, narrow emission bandwidth, red shift in fluorescence emission at high dye concentrations, relatively long excited-state lifetime, etc.
