Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 3-Ethoxy-4-((2-methylbenzyl)oxy)benzaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 270.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
3-Ethoxy-4-((2-methylbenzyl)oxy)benzaldehyde (CAS 381680-28-0), molecular formula C17H18O3 and molecular weight 270.32 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
