Chemical Structure
Description
3-(4-Bromophenyl)pentanedioic acid (CAS 1141-24-8) is a high-purity analytical reference standard with the molecular formula C11H11BrO4 and a molecular weight of 287.11 g/mol.
The molecular framework of 3-(4-Bromophenyl)pentanedioic acid (C11H11BrO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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-Bromophenyl)pentanedioic 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.
