General description
Dodecamethylpentasiloxane is an organosilicon compound that is used as a reactant or as a solvent in organic synthesis. It is also used as a precursor compound to synthesize useful compounds, such as straight-chain linear polydimethylsiloxanes (PDMS), which are widely used in industrial applications such as coatings, adhesives, and elastomers.
