Chemical Structure
Description
The molecular framework of 1,2,5-Tribromo-3-fluorobenzene (C6H2Br3F) 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).
1,2,5-Tribromo-3-fluorobenzene (CAS 2839-37-4) is a high-purity analytical reference standard with the molecular formula C6H2Br3F and a molecular weight of 332.79 g/mol.
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.
