Chemical Structure
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-Fluorobenzyl)-[1,2,4]triazolo[4,3-a]pyrazine (CAS 1159540-58-5), a certified reference material (molecular formula C12H9FN4, MW 228.23 g/mol) for analytical method development and quality control.
3-(4-Fluorobenzyl)-[1,2,4]triazolo[4,3-a]pyrazine (C12H9FN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
