Chemical Structure

3-Amino-2-fluorobenzonitrile CAS 873697-68-8 chemical structure

Description

3-Amino-2-fluorobenzonitrile (CAS 873697-68-8), molecular formula C7H5FN2 and molecular weight 136.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Amino-2-fluorobenzonitrile (C7H5FN2) is characterized by a nitrile group, fluorine substitution, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
