2,6-Dibromo-4-trifluoromethylphenol CAS 35852-57-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,6-Dibromo-4-trifluoromethylphenol.

2,6-Dibromo-4-trifluoromethylphenol (CAS 35852-57-4), molecular formula C7H3Br2F3O and molecular weight 319.90 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,6-Dibromo-4-trifluoromethylphenol (C7H3Br2F3O) is characterized by a hydroxyl group, an ether linkage, 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.
