4',4'''-(2,2-Diphenylethene-1,1-diyl)bis([1,1'-biphenyl]-4-carbaldehyde) CAS 2131097-89-5

Description

The occurrence of 4',4'''-(2,2-Diphenylethene-1,1-diyl)bis([1,1'-biphenyl]-4-carbaldehyde) 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.

4',4'''-(2,2-Diphenylethene-1,1-diyl)bis([1,1'-biphenyl]-4-carbaldehyde) (CAS 2131097-89-5), molecular formula C40H28O2 and molecular weight 540.65 g/mol, is a CATO reference standard with documented purity and traceability.

4',4'''-(2,2-Diphenylethene-1,1-diyl)bis([1,1'-biphenyl]-4-carbaldehyde) (C40H28O2) 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.
