Chemical Structure

Fluorescein Diacetate 5(6)-isothiocyanate CAS 871487-69-3 chemical structure

Description

The molecular framework of Fluorescein Diacetate 5(6)-isothiocyanate (C24H16O7C2H3NS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies Fluorescein Diacetate 5(6)-isothiocyanate (CAS 871487-69-3), a certified reference material (molecular formula C24H16O7C2H3NS, MW 489.50 g/mol) for analytical method development and quality control.
