Chemical Structure

1-Bromo-4-(difluoromethyl)-2,3-difluorobenzene CAS 1449290-34-9 chemical structure

Description

The occurrence of 1-Bromo-4-(difluoromethyl)-2,3-difluorobenzene is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Bromo-4-(difluoromethyl)-2,3-difluorobenzene (CAS 1449290-34-9), molecular formula C7H3BrF4 and molecular weight 243.00 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to fluorine/bromine substitution, an aromatic ring system, 1-Bromo-4-(difluoromethyl)-2,3-difluorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 243.00 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-Bromo-4-(difluoromethyl)-2,3-difluorobenzene 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.
