5(6)-Carboxyfluorescein Diisob

1) Cat. No.: TRC-C178340; 2) Chemical Name: 5(6)-Carboxyfluorescein Diisobutyrate; 3) CAS No.: 287111-44-8; 4) Mol. Formula: C29H24O9; 5) Mol. Weight: 516.5; 6) Packing Size: 500mg / 5g; 7) Appearence: Off-White to Pale Yellow Solid; 8) Application Notes: A protected 5(6)-Carboxyfluorescein in which the hydroxyl groups are acylated with isobutyric acid. The protection prevents self-condensation during carboxyl activation andavoids the formation of fluorophore-oligomer containg by-products associated with the use of unprotected FAM.; 9) Synonym: CFDI; 3',6'-Bis(2-methyl-1-oxopropoxy)-3-oxosSpiro[isobenzofuran-1(3H),9'-[9H]xanthene]-ar-carboxylic Acid;; 10) Solubility: DMSO, Dichloromethane, Methanol; 11) Storage condition: -20°C Freezer, Under Inert Atmosphere; 12) References: Van der Poel, J.J., et al.: Immunol.
