2-(2-Chlorophenyl)-1-phenyl-5,6,7,8-tetrahydroquinazoline-4(1H)-thione CAS 62721-97-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-Chlorophenyl)-1-phenyl-5,6,7,8-tetrahydroquinazoline-4(1H)-thione.

2-(2-Chlorophenyl)-1-phenyl-5,6,7,8-tetrahydroquinazoline-4(1H)-thione (CAS 62721-97-5), molecular formula C20H17ClN2S and molecular weight 352.88 g/mol, is a CATO reference standard with documented purity and traceability.

2-(2-Chlorophenyl)-1-phenyl-5,6,7,8-tetrahydroquinazoline-4(1H)-thione (C20H17ClN2S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 2-(2-Chlorophenyl)-1-phenyl-5,6,7,8-tetrahydroquinazoline-4(1H)-thione 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.
