4,4'-(9H-Fluorene-9,9-diyl)bis(N,N-di-p-tolylaniline) CAS 159526-57-5

Description

The occurrence of 4,4'-(9H-Fluorene-9,9-diyl)bis(N,N-di-p-tolylaniline) is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,4'-(9H-Fluorene-9,9-diyl)bis(N,N-di-p-tolylaniline) (CAS 159526-57-5), molecular formula C53H44N2 and molecular weight 708.93 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,4'-(9H-Fluorene-9,9-diyl)bis(N,N-di-p-tolylaniline) (C53H44N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
