Description

Stannane, 1,4-Naphthalenediylbis[Trimethyl-]- CAS NO 76246-38-3 is a specialized organotin compound featuring a rigid naphthalene core symmetrically substituted with trimethyltin groups. This structure makes it a valuable precursor and catalyst component in advanced material synthesis, particularly for creating polymers and hybrid organic-inorganic frameworks. It is essential for R&D and production in the electronics, specialty polymer, and fine chemical sectors where precise molecular architecture is required.

Application

• Catalyst Precursor: Used in the synthesis of catalysts for cross-coupling reactions (e.g., Stille coupling) in pharmaceutical and agrochemical intermediate manufacturing.
• Polymer Additive & Stabilizer: Acts as a heat stabilizer and catalyst in the production of polyvinyl chloride (PVC) and other halogenated polymers.
• Material Science: Serves as a key building block for creating organotin-based polymers, dendrimers, and metal-organic frameworks (MOFs) with specific electronic or optical properties.
• Semiconductor & Electronics: Employed in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes for depositing tin-containing thin films on electronic components.
• Organic Synthesis: Functions as a versatile reagent for introducing tin-functionalized naphthalene units into complex organic molecules for further transformations.
• Surface Modification Agent: Used to modify the surface properties of nanoparticles, glass, or metals to alter hydrophobicity, adhesion, or catalytic activity.

Quality Control

Our production of Stannane, 1,4-Naphthalenediylbis[Trimethyl-]- CAS NO 76246-38-3 adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. All materials are analyzed using advanced techniques including NMR, HPLC, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, 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 area 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 strong bases and incompatible materials.
