4,4',4'',4'''-((2,2',4,4',6,6'-Hexamethyl-[1,1'-biphenyl]-3,3',5,5'-tetrayl)tetrakis(ethyne-2,1-diyl))tetrabenzoicacid CAS 2306825-07-8 chemical structure

Description

The occurrence of 4,4',4'',4'''-((2,2',4,4',6,6'-Hexamethyl-[1,1'-biphenyl]-3,3',5,5'-tetrayl)tetrakis(ethyne-2,1-diyl))tetrabenzoicacid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4,4',4'',4'''-((2,2',4,4',6,6'-Hexamethyl-[1,1'-biphenyl]-3,3',5,5'-tetrayl)tetrakis(ethyne-2,1-diyl))tetrabenzoicacid (CAS 2306825-07-8), a certified reference material (molecular formula C54H38O8, MW 814.87 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 4,4',4'',4'''-((2,2',4,4',6,6'-Hexamethyl-[1,1'-biphenyl]-3,3',5,5'-tetrayl)tetrakis(ethyne-2,1-diyl))tetrabenzoicacid is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 814.87 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).

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.

As a certified reference material (CRM), 4,4',4'',4'''-((2,2',4,4',6,6'-Hexamethyl-[1,1'-biphenyl]-3,3',5,5'-tetrayl)tetrakis(ethyne-2,1-diyl))tetrabenzoicacid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
