Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(3-Chlorophenyl)-5,5-dimethyl-4-methylidene-1,3-oxazolidin-2-one.
CATO supplies 3-(3-Chlorophenyl)-5,5-dimethyl-4-methylidene-1,3-oxazolidin-2-one (CAS 59255-84-4), a certified reference material (molecular formula C12H12ClNO2, MW 237.68 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(3-Chlorophenyl)-5,5-dimethyl-4-methylidene-1,3-oxazolidin-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.68 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.
As a certified reference material (CRM), 3-(3-Chlorophenyl)-5,5-dimethyl-4-methylidene-1,3-oxazolidin-2-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.
