Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
3',5'-Bis(6-carboxynaphthalen-2-yl)-[1,1'-biphenyl]-3,5-dicarboxylic acid (CAS 2588353-96-0) is a high-purity analytical reference standard with the molecular formula C36H22O8 and a molecular weight of 582.56 g/mol.
The molecular framework of 3',5'-Bis(6-carboxynaphthalen-2-yl)-[1,1'-biphenyl]-3,5-dicarboxylic acid (C36H22O8) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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).
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.
