Description

Trimethyl-[[2,3,4,5,6-Pentakis(Trimethylsilylmethyl)Phenyl]Methyl]Silane is a highly functionalized organosilicon compound characterized by a central phenyl ring extensively substituted with trimethylsilylmethyl groups. This unique sterically hindered and highly lipophilic structure makes it a valuable advanced intermediate and ligand precursor in sophisticated synthetic chemistry. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for developing novel catalysts, specialty polymers, and complex molecular architectures.

Application

• Advanced Ligand Synthesis: Serves as a crucial precursor for synthesizing sterically demanding, electron-rich ligands used in transition metal catalysis, including cross-coupling and hydrogenation reactions.
• Pharmaceutical Intermediate: Utilized in the research and development of novel active pharmaceutical ingredients (APIs) where its bulky, lipophilic groups can influence bioavailability and metabolic stability.
• Material Science Research: Acts as a building block for creating novel silicon-based dendritic molecules, hyperbranched polymers, and organic-inorganic hybrid materials with tailored properties.
• Agrochemical Development: Employed in the synthesis of experimental fungicides, herbicides, or plant growth regulators that benefit from its specific steric and electronic profile.
• Surface Modification Agent: Can be investigated for modifying material surfaces to impart specific hydrophobic or release characteristics.
• Catalyst Development: Used to develop novel organometallic catalysts for asymmetric synthesis and other specialized organic transformations.

Quality Control

Our production of Trimethyl-[[2,3,4,5,6-Pentakis(Trimethylsilylmethyl)Phenyl]Methyl]Silane adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity for research and development applications. Identity and purity are confirmed via advanced analytical techniques including NMR (¹H, ¹³C, ²⁹Si), GC-MS, and HPLC. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment.

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 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.
