2,4-Difluoro-3-(trifluoromethyl)benzaldehyde CAS 134099-30-2

Description

The occurrence of 2,4-Difluoro-3-(trifluoromethyl)benzaldehyde is closely related to 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.

2,4-Difluoro-3-(trifluoromethyl)benzaldehyde (CAS 134099-30-2), molecular formula C8H3F5O and molecular weight 210.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,4-Difluoro-3-(trifluoromethyl)benzaldehyde (C8H3F5O) is characterized by a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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 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.
