Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-{[(3,4-dichlorophenyl)methyl]sulfanyl}-8,9-dimethoxy-3-(propan-2-yl)-2H,3H-imidazo[1,2-c]quinazolin-2-one.
5-{[(3,4-dichlorophenyl)methyl]sulfanyl}-8,9-dimethoxy-3-(propan-2-yl)-2H,3H-imidazo[1,2-c]quinazolin-2-one (CAS 1023939-04-9) is a high-purity analytical reference standard with the molecular formula C22H21Cl2N3O3S and a molecular weight of 478.39 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 5-{[(3,4-dichlorophenyl)methyl]sulfanyl}-8,9-dimethoxy-3-(propan-2-yl)-2H,3H-imidazo[1,2-c]quinazolin-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 478.39 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.
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), 5-{[(3,4-dichlorophenyl)methyl]sulfanyl}-8,9-dimethoxy-3-(propan-2-yl)-2H,3H-imidazo[1,2-c]quinazolin-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.
