Description
As a certified reference material (CRM), 4-[(2,4-dichlorophenyl)sulfanyl]-2-[(4-methylbenzyl)sulfanyl]-5,6,7,8-tetrahydroquinazoline 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.
4-[(2,4-dichlorophenyl)sulfanyl]-2-[(4-methylbenzyl)sulfanyl]-5,6,7,8-tetrahydroquinazoline (CAS 866049-14-1), molecular formula C22H20Cl2N2S2 and molecular weight 447.44 g/mol, is a CATO reference standard with documented purity and traceability.
4-[(2,4-dichlorophenyl)sulfanyl]-2-[(4-methylbenzyl)sulfanyl]-5,6,7,8-tetrahydroquinazoline (C22H20Cl2N2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
