Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 352.02 g/mol gives 2,3-dibromo-4,5-diethoxybenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,3-dibromo-4,5-diethoxybenzaldehyde (CAS 486994-08-5) is a high-purity analytical reference standard with the molecular formula C11H12Br2O3 and a molecular weight of 352.02 g/mol.
The molecular framework of 2,3-dibromo-4,5-diethoxybenzaldehyde (C11H12Br2O3) 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. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
