Chemical Structure

4-N,N-Diphenylamino-β-phenylstilbene CAS 89114-90-9 chemical structure

Description

4-N,N-Diphenylamino-β-phenylstilbene (C32H25N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).

4-N,N-Diphenylamino-β-phenylstilbene (CAS 89114-90-9) is a high-purity analytical reference standard with the molecular formula C32H25N and a molecular weight of 423.55 g/mol.

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.
