2-(3-Bromo-2-chloro-5-(trifluoromethyl)phenyl)acetonitrile CAS 2090294-87-2

Description

The occurrence of 2-(3-Bromo-2-chloro-5-(trifluoromethyl)phenyl)acetonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(3-Bromo-2-chloro-5-(trifluoromethyl)phenyl)acetonitrile (CAS 2090294-87-2), molecular formula C9H4BrClF3N and molecular weight 298.49 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(3-Bromo-2-chloro-5-(trifluoromethyl)phenyl)acetonitrile (C9H4BrClF3N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
