Description

Bis(Triethylsilyl)Acetylene 97 is a high-purity organosilicon reagent featuring a protected acetylene unit flanked by two bulky triethylsilyl groups. This compound matters as a versatile and stable building block in advanced organic synthesis, particularly for the construction of complex molecular architectures. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries for applications requiring precise carbon-silicon bond formation.

Application

• Pharmaceutical Intermediate Synthesis: Serves as a key protected acetylene synthon in the production of active pharmaceutical ingredients (APIs) and complex drug candidates.
• Agrochemical Research: Used in the development of novel pesticides and herbicides where silicon-containing alkynes are required.
• Materials Science & Polymer Chemistry: Acts as a monomer or cross-linking agent in the synthesis of specialty silicon-based polymers and advanced materials.
• Organic Synthesis Reagent: Employed in Sonogashira coupling, hydrosilylation, and other metal-catalyzed reactions to introduce silyl-protected alkyne functionalities.
• Academic & Industrial R&D: A valuable tool for methodology development and the synthesis of novel organic compounds in research laboratories.
• Semiconductor Precursor Chemistry: Investigated for use in chemical vapor deposition (CVD) processes to deposit silicon-carbon thin films.

Quality Control

Our Bis(Triethylsilyl)Acetylene 97 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure it meets the high-purity specification of ≥97%. Certificates of Analysis (COA) with full traceability are provided to guarantee supply reliability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its highly volatile and light-sensitive nature, containers should be kept sealed and handled under an inert atmosphere (e.g., nitrogen or argon) when possible to prevent degradation and maintain purity.
