Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 5-[4-[2-(3,5-Dicarboxyphenyl)ethynyl]-1-naphthalenyl]-1,3-Benzenedicarboxylicacid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 480.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5-[4-[2-(3,5-Dicarboxyphenyl)ethynyl]-1-naphthalenyl]-1,3-Benzenedicarboxylicacid (CAS 1917295-47-6), molecular formula C28H16O8 and molecular weight 480.42 g/mol, is a CATO reference standard with documented purity and traceability.
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.
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.
