Description

7,7,15,15-Tetrakis(4-hexylphenyl)-7,15-dihydrobisthieno[2′′,3′′:4′,5′]thieno[2′,3′:4,5]thieno[2,3-d:2′,3′-d′]-s-indaceno[1,2-b:5,6-b′]dithiophene-2,10-dicarboxaldehyde (C78H74O2S8) contains a sulfone group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

7,7,15,15-Tetrakis(4-hexylphenyl)-7,15-dihydrobisthieno[2′′,3′′:4′,5′]thieno[2′,3′:4,5]thieno[2,3-d:2′,3′-d′]-s-indaceno[1,2-b:5,6-b′]dithiophene-2,10-dicarboxaldehyde (CAS 2229934-75-0), molecular formula C78H74O2S8 and molecular weight 1299.94 g/mol, is a CATO reference standard with documented purity and traceability.

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.
