5-(2-Fluorophenyl)-4-phenyl-4h-1,2,4-triazole-3-thiol CAS 311784-46-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(2-Fluorophenyl)-4-phenyl-4h-1,2,4-triazole-3-thiol.

5-(2-Fluorophenyl)-4-phenyl-4h-1,2,4-triazole-3-thiol (CAS 311784-46-0), molecular formula C14H10FN3S and molecular weight 271.31 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H10FN3S, 5-(2-Fluorophenyl)-4-phenyl-4h-1,2,4-triazole-3-thiol contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 271.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
