Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-((4-Fluorobenzyl)thio)-4-methyl-5-(1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl)-4H-1,2,4-triazole.
3-((4-Fluorobenzyl)thio)-4-methyl-5-(1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl)-4H-1,2,4-triazole (CAS 477709-31-2) is a high-purity analytical reference standard with the molecular formula C23H19FN6S and a molecular weight of 430.50 g/mol.
3-((4-Fluorobenzyl)thio)-4-methyl-5-(1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl)-4H-1,2,4-triazole (C23H19FN6S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. Halogen substitution raises its density and boiling point; 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.
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.
