Description

Rel-Ethyl(2-Methoxyphenyl)[[(1S*)-5α*-Methyl-2β*-(1-Methylethyl)Cyclohexane-1α*-Yl]Oxy]Phenylsilane CAS NO 74842-23-2 is a specialized organosilane compound featuring a complex, multi-functional molecular structure. This compound is valued for its role as a key chiral intermediate or ligand in advanced synthetic chemistry, enabling the production of high-value, optically active molecules. It is primarily utilized by pharmaceutical R&D and fine chemical synthesis sectors where precise stereochemical control is paramount.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of chiral active pharmaceutical ingredients (APIs), particularly for central nervous system or cardiovascular drugs.
• Asymmetric Catalysis: Used as a precursor or ligand in transition metal-catalyzed reactions, such as asymmetric hydrogenation or cross-coupling, to induce high enantioselectivity.
• Advanced Material Synthesis: Employed in the development of novel silicon-containing polymers or hybrid organic-inorganic materials with specific optical or mechanical properties.
• Agrochemical Research: Acts as an intermediate in the creation of new-generation, stereochemically defined pesticides and herbicides.
• Academic & Industrial R&D: A valuable tool for chemists in universities and corporate labs exploring new synthetic methodologies and complex molecule construction.

Quality Control

Every batch of our organosilane intermediates is produced under strict quality management protocols. We employ advanced analytical techniques including HPLC, GC, NMR, and chiral analysis to ensure chemical identity, high purity, and enantiomeric/excess specifications are met. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment 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 (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.
