Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 263.52 g/mol gives 3-(4-Bromo-2-chlorophenyl)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(4-Bromo-2-chlorophenyl)propanoic acid (CAS 1261725-56-7), a certified reference material (molecular formula C9H8BrClO2, MW 263.52 g/mol) for analytical method development and quality control.
The molecular framework of 3-(4-Bromo-2-chlorophenyl)propanoic acid (C9H8BrClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 3-(4-Bromo-2-chlorophenyl)propanoic acid 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.
