Chemical Structure
Description
As a certified reference material (CRM), 1,1'-(Ethane-1,2-diylbis(4,1-phenylene))bis(ethan-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.
1,1'-(Ethane-1,2-diylbis(4,1-phenylene))bis(ethan-1-one) (CAS 793-06-6), molecular formula C18H18O2 and molecular weight 266.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, 1,1'-(Ethane-1,2-diylbis(4,1-phenylene))bis(ethan-1-one) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.33 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.
