Chemical Structure
Description
The molecular framework of 2-{[(2,3-dichlorophenyl)sulfanyl]methyl}-3-phenyl-3,4-dihydroquinazolin-4-one (C21H14Cl2N2OS) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-{[(2,3-dichlorophenyl)sulfanyl]methyl}-3-phenyl-3,4-dihydroquinazolin-4-one (CAS 338957-76-9), molecular formula C21H14Cl2N2OS and molecular weight 413.32 g/mol, is a CATO reference standard with documented purity and traceability.
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), 2-{[(2,3-dichlorophenyl)sulfanyl]methyl}-3-phenyl-3,4-dihydroquinazolin-4-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.
