4-fluoro-1H-pyrrolo[2,3-b]pyridine-2-carboxylic acid CAS 1016241-77-2 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 4-fluoro-1H-pyrrolo[2,3-b]pyridine-2-carboxylic acid.

4-fluoro-1H-pyrrolo[2,3-b]pyridine-2-carboxylic acid (CAS 1016241-77-2), molecular formula C8H5FN2O2 and molecular weight 180.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-fluoro-1H-pyrrolo[2,3-b]pyridine-2-carboxylic acid (C8H5FN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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.
