N-(5-(3-Fluoropyridin-4-yl)-6-(pyridin-3-yl)pyrazin-2-yl)cyclopropanecarboxamide CAS 925676-48-8

Description

N-(5-(3-Fluoropyridin-4-yl)-6-(pyridin-3-yl)pyrazin-2-yl)cyclopropanecarboxamide (CAS 925676-48-8), molecular formula C18H14FN5O and molecular weight 335.34 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(5-(3-Fluoropyridin-4-yl)-6-(pyridin-3-yl)pyrazin-2-yl)cyclopropanecarboxamide (C18H14FN5O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
