9,9,9',9'-Tetra-p-tolyl-9H,9'H-2,2'-bifluorene CAS 854046-47-2

Description

CATO manufactures 9,9,9',9'-Tetra-p-tolyl-9H,9'H-2,2'-bifluorene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

9,9,9',9'-Tetra-p-tolyl-9H,9'H-2,2'-bifluorene (CAS 854046-47-2) is a high-purity analytical reference standard with the molecular formula C54H42 and a molecular weight of 690.91 g/mol.

Owing to a polycyclic aromatic system, 9,9,9',9'-Tetra-p-tolyl-9H,9'H-2,2'-bifluorene is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 690.91 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
