Chemical Structure
Description
4,4'-(5',5''-Bis(3-(pyridin-4-yl)phenyl)-[1,1':3',1'':3'',1'''-quaterphenyl]-3,3'''-diyl)dipyridine (CAS 1009033-96-8), molecular formula C56H38N4 and molecular weight 766.93 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4,4'-(5',5''-Bis(3-(pyridin-4-yl)phenyl)-[1,1':3',1'':3'',1'''-quaterphenyl]-3,3'''-diyl)dipyridine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 766.93 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
