1-(4-Bromo-2-fluorophenyl)urea CAS 877134-79-7

Description

The occurrence of 1-(4-Bromo-2-fluorophenyl)urea is closely related to an amide group, 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.

1-(4-Bromo-2-fluorophenyl)urea (CAS 877134-79-7) is a high-purity analytical reference standard with the molecular formula C7H6BrFN2O and a molecular weight of 233.04 g/mol.

The molecular framework of 1-(4-Bromo-2-fluorophenyl)urea (C7H6BrFN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 1-(4-Bromo-2-fluorophenyl)urea 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.
