Chemical Structure

4-Bromo-5-fluoro-2-nitrobenzaldehyde CAS 213382-40-2 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-Bromo-5-fluoro-2-nitrobenzaldehyde (CAS 213382-40-2), a certified reference material (molecular formula C7H3BrFNO3, MW 248.01 g/mol) for analytical method development and quality control.

4-Bromo-5-fluoro-2-nitrobenzaldehyde (C7H3BrFNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures 4-Bromo-5-fluoro-2-nitrobenzaldehyde 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.
