Chemical Structure
Description
The occurrence of 3-Bromo-5-ethoxy-4-((3-methylbenzyl)oxy)benzaldehyde is closely related to a steroid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromo-5-ethoxy-4-((3-methylbenzyl)oxy)benzaldehyde (CAS 428472-87-1), molecular formula C17H17BrO3 and molecular weight 349.22 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, bromine substitution, 3-Bromo-5-ethoxy-4-((3-methylbenzyl)oxy)benzaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-((3-methylbenzyl)oxy)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.
