Description
Compared with other compounds in its class, the molecular weight of 337.99 g/mol gives 3-Bromo-4-(2-bromoethoxy)-5-methoxybenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-4-(2-bromoethoxy)-5-methoxybenzaldehyde (CAS 219685-47-9), molecular formula C10H10Br2O3 and molecular weight 337.99 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Bromo-4-(2-bromoethoxy)-5-methoxybenzaldehyde (C10H10Br2O3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Bromo-4-(2-bromoethoxy)-5-methoxybenzaldehyde 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.
