Chemical Structure

3,5,6-Trifluoropyridine-2-carboxylic acid CAS 1638772-01-6 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 3,5,6-Trifluoropyridine-2-carboxylic acid.

CATO supplies 3,5,6-Trifluoropyridine-2-carboxylic acid (CAS 1638772-01-6), a certified reference material (molecular formula C6H2F3NO2, MW 177.08 g/mol) for analytical method development and quality control.

The molecular framework of 3,5,6-Trifluoropyridine-2-carboxylic acid (C6H2F3NO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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. 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.
