Chemical Structure

N,N'-((1,3-Phenylenebis(oxy))bis(4,1-phenylene))bis(2-phenylacetamide) CAS 331260-78-7 chemical structure

Description

The occurrence of N,N'-((1,3-Phenylenebis(oxy))bis(4,1-phenylene))bis(2-phenylacetamide) 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.

N,N'-((1,3-Phenylenebis(oxy))bis(4,1-phenylene))bis(2-phenylacetamide) (CAS 331260-78-7), molecular formula C34H28N2O4 and molecular weight 528.60 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N,N'-((1,3-Phenylenebis(oxy))bis(4,1-phenylene))bis(2-phenylacetamide) (C34H28N2O4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
