Chemical Structure
Description
The molecular framework of 2-iodo-4-methylsulfanyl-7,8-dihydro-6H-quinazolin-5-one (C9H9IN2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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-iodo-4-methylsulfanyl-7,8-dihydro-6H-quinazolin-5-one (CAS 2901099-36-1) is a high-purity analytical reference standard with the molecular formula C9H9IN2OS and a molecular weight of 320.15 g/mol.
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-iodo-4-methylsulfanyl-7,8-dihydro-6H-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.
