3-{[(2,4-dichlorophenyl)sulfanyl]methyl}-1H,2H,3H,5H-imidazo[2,1-b]quinazolin-5-one (CAS 478032-65-4) is a high-purity analytical reference standard with the molecular formula C17H13Cl2N3OS and a molecular weight of 378.28 g/mol.
The molecular framework of 3-{[(2,4-dichlorophenyl)sulfanyl]methyl}-1H,2H,3H,5H-imidazo[2,1-b]quinazolin-5-one (C17H13Cl2N3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-{[(2,4-dichlorophenyl)sulfanyl]methyl}-1H,2H,3H,5H-imidazo[2,1-b]quinazolin-5-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.
