3,4-Difluoro-2-trifluoromethyl-bromobenzene CAS 1242339-23-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,4-Difluoro-2-trifluoromethyl-bromobenzene.

3,4-Difluoro-2-trifluoromethyl-bromobenzene (CAS 1242339-23-6), molecular formula C7H2BrF5 and molecular weight 260.99 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,4-Difluoro-2-trifluoromethyl-bromobenzene (C7H2BrF5) is characterized by fluorine/bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
