Chemical Structure

2-Fluoro-5-hydroxy-4-nitrobenzoic acid CAS 1565323-14-9 chemical structure

Description

CATO manufactures 2-Fluoro-5-hydroxy-4-nitrobenzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies 2-Fluoro-5-hydroxy-4-nitrobenzoic acid (CAS 1565323-14-9), a certified reference material (molecular formula C7H4FNO5, MW 201.11 g/mol) for analytical method development and quality control.

The molecular framework of 2-Fluoro-5-hydroxy-4-nitrobenzoic acid (C7H4FNO5) is characterized by an amide group, 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 protonation state of its nitrogen-containing 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.
