Description

Tetramethyltin is a highly volatile organotin compound with the CAS number 594-27-4, serving as a versatile and efficient reagent in advanced material synthesis. Its primary value lies in its role as a crucial tin source for chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes, enabling the production of high-purity thin films. This product is essential for manufacturers and R&D facilities in the semiconductor, photovoltaic, and specialty glass coating industries seeking precise and reliable precursors.

Application

• As a key precursor for Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD) to create tin oxide (SnO₂) and doped tin oxide transparent conductive films.
• In the manufacturing of low-emissivity (Low-E) glass and electrochromic windows for energy-efficient buildings.
• For the production of transparent conductive oxides (TCOs) used in touch screens, flat-panel displays, and thin-film photovoltaic cells.
• As a reagent in organic synthesis for introducing methyl groups or tin functionalities into complex molecules.
• In catalysis research and the development of novel organometallic catalysts.
• For the synthesis of other organotin compounds with applications in stabilizers and biocides.

Quality Control

Our Tetramethyltin CAS NO 594-27-4 is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and Inductively Coupled Plasma (ICP) analysis, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing assay, impurity profiles, and physical properties is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, preferably under an inert atmosphere such as nitrogen or argon to prevent degradation. Keep away from heat, sparks, open flames, and oxidizing agents. Recommended storage temperature is 2-8°C (refrigerated) for long-term stability.
