N-(4-bromophenyl)-N-(naphthalen-2-yl)naphthalen-2-amine CAS 690658-65-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-bromophenyl)-N-(naphthalen-2-yl)naphthalen-2-amine.

N-(4-bromophenyl)-N-(naphthalen-2-yl)naphthalen-2-amine (CAS 690658-65-2), molecular formula C26H18BrN and molecular weight 424.33 g/mol, is a CATO reference standard with documented purity and traceability.

N-(4-bromophenyl)-N-(naphthalen-2-yl)naphthalen-2-amine (C26H18BrN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, 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).

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.

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.
