Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-5-Fluoro-2-((1-(4-fluorophenyl)ethyl)amino)-6-((5-methyl-1H-pyrazol-3-yl)amino) Nicotinonitrile.
CATO supplies (S)-5-Fluoro-2-((1-(4-fluorophenyl)ethyl)amino)-6-((5-methyl-1H-pyrazol-3-yl)amino) Nicotinonitrile (CAS 905586-69-8), a certified reference material (molecular formula C18H32F2N6, MW 370.48 g/mol) for analytical method development and quality control.
The molecular framework of (S)-5-Fluoro-2-((1-(4-fluorophenyl)ethyl)amino)-6-((5-methyl-1H-pyrazol-3-yl)amino) Nicotinonitrile (C18H32F2N6) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
