Chemical Structure

5-Fluoro-4-hydroxy-2H-chromen-2-one CAS 799262-09-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Fluoro-4-hydroxy-2H-chromen-2-one.

5-Fluoro-4-hydroxy-2H-chromen-2-one (CAS 799262-09-2) is a high-purity analytical reference standard with the molecular formula C9H5FO3 and a molecular weight of 180.13 g/mol.

The molecular framework of 5-Fluoro-4-hydroxy-2H-chromen-2-one (C9H5FO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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).

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.

As a certified reference material (CRM), 5-Fluoro-4-hydroxy-2H-chromen-2-one 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.
