Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 273.12 g/mol gives 5-Bromo-2,4-diethoxybenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-2,4-diethoxybenzaldehyde (CAS 223699-52-3), molecular formula C11H13BrO3 and molecular weight 273.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Bromo-2,4-diethoxybenzaldehyde (C11H13BrO3) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 5-Bromo-2,4-diethoxybenzaldehyde 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.
