Produktbeschreibung

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 Purity: 98% Appearance: Yellow solid Melting Point: >138C (dec.) Solubility: Chloroform (Slightly), Methanol (Slightly) Method for Determining Identity: Proton NMR 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 -20C for 6 months after receipt. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Store Under inert atmosphere.
