4-((4-(Diethylamino)benzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione CAS 573971-68-3 chemical structure

Description

The occurrence of 4-((4-(Diethylamino)benzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-((4-(Diethylamino)benzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 573971-68-3) is a high-purity analytical reference standard with the molecular formula C19H20FN5S and a molecular weight of 369.46 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, 4-((4-(Diethylamino)benzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 369.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 4-((4-(Diethylamino)benzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-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.
