Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1-(2,5-Dimethylphenyl)-2-phenylethanone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 224.30 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.
1-(2,5-Dimethylphenyl)-2-phenylethanone (CAS 41840-98-6), molecular formula C16H16O and molecular weight 224.30 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.
As a certified reference material (CRM), 1-(2,5-Dimethylphenyl)-2-phenylethanone 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.
