Description

Compared with other compounds in its class, the molecular weight of 606.75 g/mol gives 5',5"-Bis(4-hydroxyphenyl)-2',2",4',4",6',6"-hexamethyl-[1,1':3',1":3",1"'-quaterphenyl]-4,4"'-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5',5"-Bis(4-hydroxyphenyl)-2',2",4',4",6',6"-hexamethyl-[1,1':3',1":3",1"'-quaterphenyl]-4,4"'-diol (CAS 868046-54-2) is a high-purity analytical reference standard with the molecular formula C42H38O4 and a molecular weight of 606.75 g/mol.

5',5"-Bis(4-hydroxyphenyl)-2',2",4',4",6',6"-hexamethyl-[1,1':3',1":3",1"'-quaterphenyl]-4,4"'-diol (C42H38O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 5',5"-Bis(4-hydroxyphenyl)-2',2",4',4",6',6"-hexamethyl-[1,1':3',1":3",1"'-quaterphenyl]-4,4"'-diol 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.
