Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(4-Chlorophenyl)(4-methoxy-3-methylphenyl)methanone (CAS 68947-53-5) is a high-purity analytical reference standard with the molecular formula C15H13ClO2 and a molecular weight of 260.72 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, (4-Chlorophenyl)(4-methoxy-3-methylphenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (4-Chlorophenyl)(4-methoxy-3-methylphenyl)methanone 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.
