Description
Compared with other compounds in its class, the molecular weight of 385.25 g/mol gives 3-Bromo-5-ethoxy-4-(1-naphthylmethoxy)benzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-5-ethoxy-4-(1-naphthylmethoxy)benzaldehyde (CAS 426231-02-9) is a high-purity analytical reference standard with the molecular formula C20H17BrO3 and a molecular weight of 385.25 g/mol.
3-Bromo-5-ethoxy-4-(1-naphthylmethoxy)benzaldehyde (C20H17BrO3) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-5-ethoxy-4-(1-naphthylmethoxy)benzaldehyde 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.
