5-(2,3-Difluorophenyl)cyclohexane-1,3-dione CAS 1503065-06-2

Description

The occurrence of 5-(2,3-Difluorophenyl)cyclohexane-1,3-dione is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(2,3-Difluorophenyl)cyclohexane-1,3-dione (CAS 1503065-06-2), molecular formula C12H10F2O2 and molecular weight 224.20 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H10F2O2, 5-(2,3-Difluorophenyl)cyclohexane-1,3-dione contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 224.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
