Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 9,9,9′,9′-Tetraoctyl-2,2′-bi-9H-fluorene (CAS 302554-79-6), a certified reference material (molecular formula C58H82, MW 779.27 g/mol) for analytical method development and quality control.
The molecular framework of 9,9,9′,9′-Tetraoctyl-2,2′-bi-9H-fluorene (C58H82) is characterized by a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
