Description

1,1'-[2-[(Trimethylsilyl)Oxy]-5-[[4-[(Trimethylsilyl)Oxy]-3-[1-[(Trimethylsilyl)Oxy]-1-Pentenyl]Phenyl]Methyl]-1,3-Phenylene]Bis(1-Pentanone) is a specialized organosilicon compound featuring multiple trimethylsilyl (TMS) protecting groups and a diketone backbone. This chemical is a critical synthetic intermediate in advanced organic synthesis, particularly valued for its role in constructing complex molecular architectures. It is primarily required by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for the production of high-value target molecules.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel active pharmaceutical ingredients (APIs), especially for complex polycyclic or sterically hindered targets.
• Agrochemical Synthesis: Used in the research and development of new-generation pesticides and herbicides where specific silicon-containing motifs are required for bioactivity.
• Advanced Material Precursor: Serves as a monomer or cross-linking agent in the development of specialty polymers, resins, and silicon-based hybrid materials.
• Organic Synthesis Reagent: Employed in multi-step synthetic routes as a protected intermediate, leveraging the TMS groups for selective deprotection strategies.
• Chemical Research: Utilized in academic and industrial laboratories for methodological development in synthetic chemistry, including catalysis and new bond-forming reactions.
• Fine Chemical Production: Intermediate in the manufacture of complex flavors, fragrances, and other high-value specialty chemicals.

Quality Control

Our production of 1,1'-[2-[(Trimethylsilyl)Oxy]-5-[[4-[(Trimethylsilyl)Oxy]-3-[1-[(Trimethylsilyl)Oxy]-1-Pentenyl]Phenyl]Methyl]-1,3-Phenylene]Bis(1-Pentanone) adheres to stringent quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications and test results are provided and available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat and incompatible materials.
