Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 3-(3-Chlorophenyl)-3',5'-dichloropropiophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 313.61 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.
3-(3-Chlorophenyl)-3',5'-dichloropropiophenone (CAS 898787-40-1), molecular formula C15H11Cl3O and molecular weight 313.61 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), 3-(3-Chlorophenyl)-3',5'-dichloropropiophenone 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.
