(4,4''-Di(10H-phenoxazin-10-yl)-[1,1':4',1''-terphenyl]-2',5'-diyl)bis(p-tolylmethanone) CAS 1647121-46-7

Description

The occurrence of (4,4''-Di(10H-phenoxazin-10-yl)-[1,1':4',1''-terphenyl]-2',5'-diyl)bis(p-tolylmethanone) is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(4,4''-Di(10H-phenoxazin-10-yl)-[1,1':4',1''-terphenyl]-2',5'-diyl)bis(p-tolylmethanone) (CAS 1647121-46-7), molecular formula C58H40N2O4 and molecular weight 828.95 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (4,4''-Di(10H-phenoxazin-10-yl)-[1,1':4',1''-terphenyl]-2',5'-diyl)bis(p-tolylmethanone) (C58H40N2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).

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.
