Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Bromoethyl)-3-fluoro-5-(trifluoromethyl)benzene.
1-(2-Bromoethyl)-3-fluoro-5-(trifluoromethyl)benzene (CAS 955036-79-0) is a high-purity analytical reference standard with the molecular formula C9H7BrF4 and a molecular weight of 271.05 g/mol.
The molecular framework of 1-(2-Bromoethyl)-3-fluoro-5-(trifluoromethyl)benzene (C9H7BrF4) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
