Chemical Structure

1,7-Diphenyl-4-hepten-3-one CAS 79559-59-4 chemical structure

Description

As a certified reference material (CRM), 1,7-Diphenyl-4-hepten-3-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.

1,7-Diphenyl-4-hepten-3-one (CAS 79559-59-4), molecular formula C19H20O and molecular weight 264.36 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, 1,7-Diphenyl-4-hepten-3-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 264.36 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.
