5-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]ethyl}-4-phenyl-4H-1,2,4-triazole-3-thiol CAS 339010-57-0

Description

As a certified reference material (CRM), 5-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]ethyl}-4-phenyl-4H-1,2,4-triazole-3-thiol 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.

5-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]ethyl}-4-phenyl-4H-1,2,4-triazole-3-thiol (CAS 339010-57-0), molecular formula C16H12ClF3N4S and molecular weight 384.81 g/mol, is a CATO reference standard with documented purity and traceability.

5-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]ethyl}-4-phenyl-4H-1,2,4-triazole-3-thiol (C16H12ClF3N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/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.
