Chemical Structure

4-MONOIODOFLUORESCEIN,DISODIUM SALT CAS 52010-86-3 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO supplies 4-MONOIODOFLUORESCEIN,DISODIUM SALT (CAS 52010-86-3), a certified reference material (molecular formula C20H9IO5Na, MW 479.18 g/mol) for analytical method development and quality control.

The molecular framework of 4-MONOIODOFLUORESCEIN,DISODIUM SALT (C20H9IO5Na) is characterized by a salt form, a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), 4-MONOIODOFLUORESCEIN,DISODIUM SALT meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
