Chemical Structure
Description
CATO supplies 8-Fluoro[1,2,4]triazolo[4,3-c]pyrimidin-5-amine (CAS 2096986-18-2), a certified reference material (molecular formula C5H4FN5, MW 153.12 g/mol) for analytical method development and quality control.
Based on its molecular formula C5H4FN5, 8-Fluoro[1,2,4]triazolo[4,3-c]pyrimidin-5-amine contains a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 153.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
