Description

(6-Methoxynaphthalen-2-Ylethynyl)Trimethylsilane, 97% is a high-purity organosilicon intermediate featuring a naphthalene core functionalized with a methoxy group and a trimethylsilylethynyl moiety. This compound is valued for its role as a versatile building block in advanced organic synthesis, particularly in cross-coupling reactions and the construction of complex molecular architectures. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries for the development of novel active ingredients and functional organic materials.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the synthesis of potential drug candidates, especially those with extended aromatic systems.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides that require specific naphthalene-based scaffolds.
• Material Science Precursor: Acts as a monomer or building block for organic semiconductors, liquid crystals, and advanced polymers.
• Cross-Coupling Reactions: Utilized in Sonogashira, Heck, and other palladium-catalyzed coupling reactions to introduce acetylene-linked aromatic systems.
• Organic Light-Emitting Diodes (OLEDs): Investigated for use in the synthesis of electron-transport or emissive layer materials.
• Laboratory Scale Synthesis: Employed in academic and industrial research for method development and exploring new chemical spaces.

Quality Control

Our (6-Methoxynaphthalen-2-Ylethynyl)Trimethylsilane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and a minimum purity of 97%. Each lot is analyzed using advanced spectroscopic and chromatographic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment and is available upon request.

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.
