Description
As a certified reference material (CRM), 1-(3-Chloro-4-methylphenyl)-3-methylbutan-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-(3-Chloro-4-methylphenyl)-3-methylbutan-1-one (CAS 1267232-32-5) is a high-purity analytical reference standard with the molecular formula C12H15ClO and a molecular weight of 210.70 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1-(3-Chloro-4-methylphenyl)-3-methylbutan-1-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 210.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
