2-Fluoro-3-iodoisonicotinonitrile CAS 898854-64-3 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 2-Fluoro-3-iodoisonicotinonitrile.

2-Fluoro-3-iodoisonicotinonitrile (CAS 898854-64-3), molecular formula C6H2FIN2 and molecular weight 248.00 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H2FIN2, 2-Fluoro-3-iodoisonicotinonitrile contains a nitrile group, fluorine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 248.00 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
