3-(((4-Bromobenzyl)sulfinyl)methyl)-4-ethyl-5-((4-fluorobenzyl)thio)-4H-1,2,4-triazole CAS 344275-25-8

Description

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.

CATO supplies 3-(((4-Bromobenzyl)sulfinyl)methyl)-4-ethyl-5-((4-fluorobenzyl)thio)-4H-1,2,4-triazole (CAS 344275-25-8), a certified reference material (molecular formula C19H19BrFN3OS2, MW 468.41 g/mol) for analytical method development and quality control.

3-(((4-Bromobenzyl)sulfinyl)methyl)-4-ethyl-5-((4-fluorobenzyl)thio)-4H-1,2,4-triazole (C19H19BrFN3OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
