| Description | 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. Synonyms: CFDI; 3’,6’-Bis(2-methyl-1-oxopropoxy)-3-oxosSpiro[isobenzofuran-1(3H),9’-[9H]xanthene]-ar-carboxylic Acid CAS Number: 287111-44-8 Molecular Formula: C29H24O9 Molecular Weight: 516.5 Appearance: Supplied as a yellow solid Purity: ≥98% Melting Point: 133-138ºC (dec) Solubility: Chloroform (Slightly), Methanol (Slightly) Method for Determining Identity: Proton NMR (CDCl3) Spectroscopic and Mass Spectrometric Analysis TLC Conditions: SiO2; Dichloromethane: Methanol; 9:1; Visualized with UV and AMCS; Rf=0.35 Ethly Acetate Content: ~2% Atmoshere: Inert Gas Storage and Stability: May be stored at RT for short-term only. Long-term storage is recommended at -20°C for 6 months after receipt. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Store Under inert atmosphere.
