Chemical Structure

1,3-Difluoro-4-nitro-2-(trifluoromethyl)benzene CAS 123973-36-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 227.09 g/mol gives 1,3-Difluoro-4-nitro-2-(trifluoromethyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,3-Difluoro-4-nitro-2-(trifluoromethyl)benzene (CAS 123973-36-4), a certified reference material (molecular formula C7H2F5NO2, MW 227.09 g/mol) for analytical method development and quality control.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 1,3-Difluoro-4-nitro-2-(trifluoromethyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 227.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 1,3-Difluoro-4-nitro-2-(trifluoromethyl)benzene 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.
