2-[(4-Chlorophenyl)methyl]-4-{[(2,4-dichlorophenyl)methyl]sulfanyl}quinazoline CAS 303149-26-0

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

2-[(4-Chlorophenyl)methyl]-4-{[(2,4-dichlorophenyl)methyl]sulfanyl}quinazoline (CAS 303149-26-0), molecular formula C22H15Cl3N2S and molecular weight 445.79 g/mol, is a CATO reference standard with documented purity and traceability.

2-[(4-Chlorophenyl)methyl]-4-{[(2,4-dichlorophenyl)methyl]sulfanyl}quinazoline (C22H15Cl3N2S) 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).

As a certified reference material (CRM), 2-[(4-Chlorophenyl)methyl]-4-{[(2,4-dichlorophenyl)methyl]sulfanyl}quinazoline 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.
