Chemical Structure

1,2-Dibromo-4-difluoromethoxy-5-nitrobenzene CAS 1806293-53-7 chemical structure

Description

As a certified reference material (CRM), 1,2-Dibromo-4-difluoromethoxy-5-nitrobenzene 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.

CATO supplies 1,2-Dibromo-4-difluoromethoxy-5-nitrobenzene (CAS 1806293-53-7), a certified reference material (molecular formula C7H3Br2F2NO3, MW 346.91 g/mol) for analytical method development and quality control.

Structurally, 1,2-Dibromo-4-difluoromethoxy-5-nitrobenzene (C7H3Br2F2NO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 346.91 g/mol, it falls into the moderately-high-molecular-weight range. 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.
