Chemical Structure
Description
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.
4',5'-Bis(4-formylphenyl)-[1,1':2',1''-terphenyl]-4,4''-dicarbaldehyde (CAS 883835-33-4), molecular formula C34H22O4 and molecular weight 494.54 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4',5'-Bis(4-formylphenyl)-[1,1':2',1''-terphenyl]-4,4''-dicarbaldehyde (C34H22O4) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
CATO manufactures 4',5'-Bis(4-formylphenyl)-[1,1':2',1''-terphenyl]-4,4''-dicarbaldehyde 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.
