Trivinylphosphine (65% in THF, stabilized with hydroquinone) is a highly reactive organophosphorus compound primarily used in polymerization and crosslinking applications. The inclusion of hydroquinone as a stabilizer ensures enhanced shelf life by inhibiting premature polymerization. Supplied as a 65% solution in tetrahydrofuran (THF), it offers convenient handling and precise dosing in synthetic processes. Its trifunctional vinyl groups enable efficient participation in radical and anionic reactions, making it valuable for creating phosphine-containing polymers or as a ligand precursor in coordination chemistry. The solution format reduces hazards associated with neat handling while maintaining reactivity. Suitable for controlled environments due to its air- and moisture-sensitive nature.
