Chemical Structure
Description
As a certified reference material (CRM), Methyl 2-bromo-4-formylbenzoate 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.
Methyl 2-bromo-4-formylbenzoate (CAS 90484-52-9) is a high-purity analytical reference standard with the molecular formula C9H7BrO3 and a molecular weight of 243.05 g/mol.
The molecular framework of Methyl 2-bromo-4-formylbenzoate (C9H7BrO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
