Methyl 2-Bromo-5-fluoro-3-nitrobenzoate CAS 328547-12-2

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.

Methyl 2-Bromo-5-fluoro-3-nitrobenzoate (CAS 328547-12-2), molecular formula C8H5BrFNO4 and molecular weight 278.03 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl 2-Bromo-5-fluoro-3-nitrobenzoate (C8H5BrFNO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. 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).

As a certified reference material (CRM), Methyl 2-Bromo-5-fluoro-3-nitrobenzoate 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.
