4,4′,4′′,4′′′-(1,2-Ethenediylidene)tetrakis[N,N-dimethylbenzenamine] CAS 1261-86-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4′,4′′,4′′′-(1,2-Ethenediylidene)tetrakis[N,N-dimethylbenzenamine].

4,4′,4′′,4′′′-(1,2-Ethenediylidene)tetrakis[N,N-dimethylbenzenamine] (CAS 1261-86-5), molecular formula C34H40N4 and molecular weight 504.71 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,4′,4′′,4′′′-(1,2-Ethenediylidene)tetrakis[N,N-dimethylbenzenamine] (C34H40N4) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
