Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 232.05 g/mol gives 4'-Bromo-3'-fluoroacetanilide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4'-Bromo-3'-fluoroacetanilide (CAS 351-30-4) is a high-purity analytical reference standard with the molecular formula C8H7BrFNO and a molecular weight of 232.05 g/mol.
The molecular framework of 4'-Bromo-3'-fluoroacetanilide (C8H7BrFNO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 4'-Bromo-3'-fluoroacetanilide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
