Chemical Structure
Description
Based on its molecular formula C12H21BrSi2, (5-Bromo-1,3-phenylene)bis(trimethylsilane) contains bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 301.37 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.
