(3-Bromophenyl)(2,3-difluorophenyl)methanone CAS 1220124-56-0

Description

The occurrence of (3-Bromophenyl)(2,3-difluorophenyl)methanone is closely related to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3-Bromophenyl)(2,3-difluorophenyl)methanone (CAS 1220124-56-0), molecular formula C13H7BrF2O and molecular weight 297.09 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, (3-Bromophenyl)(2,3-difluorophenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 297.09 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.

As a certified reference material (CRM), (3-Bromophenyl)(2,3-difluorophenyl)methanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
