Chemical Structure
Description
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.
CATO supplies 5-(3-fluoro-4-methoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrazin-2-amine (CAS 2007921-00-6), a certified reference material (molecular formula C12H10FN5O, MW 259.24 g/mol) for analytical method development and quality control.
Structurally, 5-(3-fluoro-4-methoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrazin-2-amine (C12H10FN5O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 259.24 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
