Chemical Structure

N,N-Dimethyl-4-(trimethylsilyl)aniline CAS 16087-24-4 chemical structure

Description

N,N-Dimethyl-4-(trimethylsilyl)aniline (CAS 16087-24-4) is a high-purity analytical reference standard with the molecular formula C11H19NSi and a molecular weight of 193.36 g/mol.

Owing to a nitrile group, N,N-Dimethyl-4-(trimethylsilyl)aniline is typically white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 193.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
