Chemical Structure
Description
5-bromonaphthalene-1,4-dicarboxylic acid (CAS CATO-C4X-26288) is a high-purity analytical reference standard with the molecular formula C12H7BrO4 and a molecular weight of 295.09 g/mol.
The molecular framework of 5-bromonaphthalene-1,4-dicarboxylic acid (C12H7BrO4) 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. 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 5-bromonaphthalene-1,4-dicarboxylic 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.
