2,2-Difluoro-2-(3-oxocyclopentyl)acetic acid CAS 1780193-51-2

Description

Compared with other compounds in its class, the molecular weight of 178.13 g/mol gives 2,2-Difluoro-2-(3-oxocyclopentyl)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,2-Difluoro-2-(3-oxocyclopentyl)acetic acid (CAS 1780193-51-2), molecular formula C7H8F2O3 and molecular weight 178.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,2-Difluoro-2-(3-oxocyclopentyl)acetic acid (C7H8F2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
