Chemical Structure

2,2-difluoro-2-(4-phenyl-1H-1,2,3-triazol-1-yl)acetic acid CAS 1989672-28-7 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 2,2-difluoro-2-(4-phenyl-1H-1,2,3-triazol-1-yl)acetic acid.

2,2-difluoro-2-(4-phenyl-1H-1,2,3-triazol-1-yl)acetic acid (CAS 1989672-28-7) is a high-purity analytical reference standard with the molecular formula C10H7F2N3O2 and a molecular weight of 239.18 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 2,2-difluoro-2-(4-phenyl-1H-1,2,3-triazol-1-yl)acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 239.18 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.
