Chemical Structure

2-amino-2-(2,5-difluorophenyl)acetic acid hydrochloride CAS 1955498-48-2 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 2-amino-2-(2,5-difluorophenyl)acetic acid hydrochloride.

2-amino-2-(2,5-difluorophenyl)acetic acid hydrochloride (CAS 1955498-48-2) is a high-purity analytical reference standard with the molecular formula C8H7F2NO2HCl and a molecular weight of 223.60 g/mol.

The molecular framework of 2-amino-2-(2,5-difluorophenyl)acetic acid hydrochloride (C8H7F2NO2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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 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.
