Chemical Structure
Description
Owing to fluorine substitution, 1-(Trimethylsilyl)-3,4-difluorobenzene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.27 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).
