3-(4-Fluoro-1H-imidazol-5-yl)propanoic acid CAS 959243-70-0

Description

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.

3-(4-Fluoro-1H-imidazol-5-yl)propanoic acid (CAS 959243-70-0), molecular formula C6H7FN2O2 and molecular weight 158.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(4-Fluoro-1H-imidazol-5-yl)propanoic acid (C6H7FN2O2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
