Chemical Structure
Description
3-(2-Fluorophenyl)-4-(((2-hydroxynaphthalen-1-yl)methylene)amino)-1H-1,2,4-triazole-5(4H)-thione (CAS 676333-72-5), molecular formula C19H13FN4OS and molecular weight 364.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 3-(2-Fluorophenyl)-4-(((2-hydroxynaphthalen-1-yl)methylene)amino)-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 364.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
