Chemical Structure

Butyldimethyl(pentyl)silane CAS 71864-45-4 chemical structure

Description

The occurrence of Butyldimethyl(pentyl)silane is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Butyldimethyl(pentyl)silane (CAS 71864-45-4), a certified reference material (molecular formula C11H26Si, MW 186.41 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H26Si, Butyldimethyl(pentyl)silane contains an organic framework; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 186.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
