2-(5-((3,4-Dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)thieno[2,3-b]quinoline CAS 478260-38-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(5-((3,4-Dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)thieno[2,3-b]quinoline.

CATO supplies 2-(5-((3,4-Dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)thieno[2,3-b]quinoline (CAS 478260-38-7), a certified reference material (molecular formula C22H16Cl2N4S2, MW 471.43 g/mol) for analytical method development and quality control.

2-(5-((3,4-Dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)thieno[2,3-b]quinoline (C22H16Cl2N4S2) 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.

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-(5-((3,4-Dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)thieno[2,3-b]quinoline 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.
