Descrizione generale

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.

Applicazioni

  • Adsorption Characteristics of Dodecamethylpentasiloxane from Landfill Leachate: This study investigates the adsorption behavior of dodecamethylpentasiloxane in municipal solid waste, crucial for environmental chemists and waste management specialists (Q Kong et al., 2022).
  • Toxicity of Silicone Oil: This research evaluates the cytotoxicity of liquid low molecular weight cyclosiloxanes including dodecamethylpentasiloxane, significant for drug discovery chemists considering silicone oil applications (Y Chen et al., 2021).
  • Bioaccumulation of Volatile Methylsiloxanes: Review of how volatile methylsiloxanes like dodecamethylpentasiloxane bioaccumulate in aquatic ecosystems, useful for environmental scientists and regulatory bodies (F Bernardo et al., 2022).
  • Solid MRI Contrast Agents: Describes the use of dodecamethylpentasiloxane as a contrast agent for in vivo oxygen sensing, relevant to biomedical research and materials science (VH Liu et al., 2014).
  • Effective Removal of Methyl Siloxane by Sewage Sludge Microbes: Discusses biodegradation of dodecamethylpentasiloxane, pertinent for environmental chemists and waste treatment research (Y Wang et al., 2019).
