Chemical Structure

2,3-Difluoro-5-nitrobenzodifluoride CAS 1804516-11-7 chemical structure

Description

CATO supplies 2,3-Difluoro-5-nitrobenzodifluoride (CAS 1804516-11-7), a certified reference material (molecular formula C7H3F4NO2, MW 209.10 g/mol) for analytical method development and quality control.

2,3-Difluoro-5-nitrobenzodifluoride (C7H3F4NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 2,3-Difluoro-5-nitrobenzodifluoride 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.
