9,9,9',9',9'',9''-Hexa-p-tolyl-9H,9'H,9''H-2,2':7',2''-terfluorene CAS 474918-42-8

Description

The occurrence of 9,9,9',9',9'',9''-Hexa-p-tolyl-9H,9'H,9''H-2,2':7',2''-terfluorene is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 9,9,9',9',9'',9''-Hexa-p-tolyl-9H,9'H,9''H-2,2':7',2''-terfluorene (CAS 474918-42-8), a certified reference material (molecular formula C81H62, MW 1035.36 g/mol) for analytical method development and quality control.

9,9,9',9',9'',9''-Hexa-p-tolyl-9H,9'H,9''H-2,2':7',2''-terfluorene (C81H62) contains a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

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.
