N,N-Diphenyl-[2,2'-bithiophen]-5-amine CAS 554416-50-1

Description

Compared with other compounds in its class, the molecular weight of 333.47 g/mol gives N,N-Diphenyl-[2,2'-bithiophen]-5-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N,N-Diphenyl-[2,2'-bithiophen]-5-amine (CAS 554416-50-1) is a high-purity analytical reference standard with the molecular formula C20H15NS2 and a molecular weight of 333.47 g/mol.

The molecular framework of N,N-Diphenyl-[2,2'-bithiophen]-5-amine (C20H15NS2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 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.
