Chemical Structure

Trimethyl(phenylethynyl)stannane CAS 1199-95-7 chemical structure

Description

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.

Trimethyl(phenylethynyl)stannane (CAS 1199-95-7) is a high-purity analytical reference standard with the molecular formula C11H14Sn and a molecular weight of 264.94 g/mol.

Based on its molecular formula C11H14Sn, Trimethyl(phenylethynyl)stannane contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 264.94 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
