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-Bromo-3-((trifluoromethyl)sulfonyl)benzene.
1-Bromo-3-((trifluoromethyl)sulfonyl)benzene (CAS 2728-70-3) is a high-purity analytical reference standard with the molecular formula C7H4BrF3O2S and a molecular weight of 289.07 g/mol.
The molecular framework of 1-Bromo-3-((trifluoromethyl)sulfonyl)benzene (C7H4BrF3O2S) is characterized by a sulfone group, a carboxylic acid group, 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. 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.
