Chemical Structure

2-((3-(Trifluoromethyl)phenyl)amino)isonicotinic acid CAS 42729-22-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 282.22 g/mol gives 2-((3-(Trifluoromethyl)phenyl)amino)isonicotinic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-((3-(Trifluoromethyl)phenyl)amino)isonicotinic acid (CAS 42729-22-6), molecular formula C13H9F3N2O2 and molecular weight 282.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 2-((3-(Trifluoromethyl)phenyl)amino)isonicotinic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 282.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
