Useful:

• Chemical Classes: Metals -> Metalloid Compounds (Silicon)
• Canonical SMILES: C[Si](C)(C)O[Si](C)(C)O[Si](C)(C)O[Si](C)(C)C
• Uses: A non-cyclic silicone oligomer. Used in the methylation of mercury(II) salts. Study shows that it transformed by a specific microflora and in the natural environment degraded by mechanisms similar to other organic compounds. Decamethyltetrasiloxane can be used as a basis for silicone oils or fluids designed to withstand extremes of temp; as a foam suppressant in petroleum lubricating oil.
