Usage

General Description

The chemical [((1a,3b,5E,7E)-9,10-Secocholesta-5,7,10(19)-triene-1,3-diyl)bis(oxy)]bis[(1,1-dimethylethyl)dimethylsilane] is a complex compound that consists of a secocholesta-5,7,10(19)-triene backbone with oxy and dimethylsilane groups attached. The molecule also contains 1,1-dimethylethyl groups. [[(1a,3b,5E,7E)-9,10-Secocholesta-5,7,10(19)-triene-1,3-diyl]bis(oxy)]bis[(1,1-dimethylethyl)dimethylsilane] is likely to have a variety of applications in the fields of organic chemistry, material science, and pharmaceuticals due to the presence of the secocholesta backbone, which is a precursor for the synthesis of vitamin D3, and the dimethylsilane groups, which are commonly found in silicone polymers. The specific properties and potential uses of this compound would need to be further investigated through experimental research.
