Chemical Structure
Description
The occurrence of 2-Bromo-4-[(4-trifluoromethyl)phenyl]-1-butene is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-4-[(4-trifluoromethyl)phenyl]-1-butene (CAS 951889-60-4) is a high-purity analytical reference standard with the molecular formula C11H10BrF3 and a molecular weight of 279.10 g/mol.
The molecular framework of 2-Bromo-4-[(4-trifluoromethyl)phenyl]-1-butene (C11H10BrF3) is characterized by fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
