Usage

General Description

1,3-Bis[(trimethylsilyl)ethynyl]benzene is a chemical compound that is also known as TES-protected diyne. It is a symmetrical diacetylene compound that is frequently used in organic synthesis to construct complex molecular frameworks. The trimethylsilyl groups provide protection for the ethynyl functional groups, and can be removed under mild conditions to reveal the reactive alkyne groups. 1,3-BIS[(TRIMETHYLSILYL)ETHYNYL]BENZENE has been utilized in the preparation of functional materials, such as liquid crystals, organic semiconductors, and polymers. Additionally, it has also been employed in the development of novel drug molecules and in the study of molecular structure and reactivity.
