Chemical Structure
Description
(2E)-3-[4-(Benzyloxy)phenyl]-1-(4-ethylphenyl)prop-2-en-1-one (CAS 1354941-37-9), molecular formula C24H22O2 and molecular weight 342.43 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, (2E)-3-[4-(Benzyloxy)phenyl]-1-(4-ethylphenyl)prop-2-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.43 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).
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), (2E)-3-[4-(Benzyloxy)phenyl]-1-(4-ethylphenyl)prop-2-en-1-one 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.
