Chemical Structure
Description
The molecular framework of 3-(2-Fluorophenyl)-4-(((5-methylthiophen-2-yl)methylene)amino)-1H-1,2,4-triazole-5(4H)-thione (C14H11FN4S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3-(2-Fluorophenyl)-4-(((5-methylthiophen-2-yl)methylene)amino)-1H-1,2,4-triazole-5(4H)-thione (CAS 573694-24-3), molecular formula C14H11FN4S2 and molecular weight 318.39 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
