Description

Compared with other compounds in its class, the molecular weight of 834.86 g/mol gives 6,6',6",6'"-([1,1'-Biphenyl]-3,3',5,5'-tetrayl)tetrakis(2-naphthoic acid) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6,6',6",6'"-([1,1'-Biphenyl]-3,3',5,5'-tetrayl)tetrakis(2-naphthoic acid) (CAS 2355235-50-4), molecular formula C56H34O8 and molecular weight 834.86 g/mol, is a CATO reference standard with documented purity and traceability.

6,6',6",6'"-([1,1'-Biphenyl]-3,3',5,5'-tetrayl)tetrakis(2-naphthoic acid) (C56H34O8) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 6,6',6",6'"-([1,1'-Biphenyl]-3,3',5,5'-tetrayl)tetrakis(2-naphthoic 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.
