Chemical Structure

N,N-Di-p-tolylthiophen-2-amine CAS 89331-93-1 chemical structure

Description

The occurrence of N,N-Di-p-tolylthiophen-2-amine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N,N-Di-p-tolylthiophen-2-amine (CAS 89331-93-1) is a high-purity analytical reference standard with the molecular formula C18H17NS and a molecular weight of 279.40 g/mol.

The molecular framework of N,N-Di-p-tolylthiophen-2-amine (C18H17NS) 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 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.
