Description

Tetrakis(Dimethylamino)Tin CAS NO 1066-77-9 is a highly reactive organotin compound primarily used as a precursor in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes. Its value lies in its ability to serve as a volatile, high-purity tin source for depositing tin-containing thin films and nanomaterials. This chemical is essential for manufacturers and R&D facilities in the semiconductor, electronics, and advanced materials sectors seeking to develop next-generation coatings and devices.

Application

• Semiconductor Manufacturing: As a key precursor for depositing tin oxide (SnO2) or doped tin oxide films via CVD and ALD for transparent conductive oxides (TCOs) in displays and photovoltaics.
• Advanced Materials Synthesis: Used in the production of specialized catalysts and as a reagent for introducing tin into complex organometallic frameworks.
• Thin Film Electronics: Enables the fabrication of gas sensors, optoelectronic devices, and resistive memory elements through precise thin film deposition.
• Research & Development: Serves as a fundamental building block in academic and industrial labs for exploring new tin-based compounds and nanomaterials.
• Polymer Chemistry: Can act as a catalyst or co-catalyst in specific polymerization reactions and cross-linking processes.

Quality Control

Our Tetrakis(Dimethylamino)Tin is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity, critical for sensitive deposition processes. Each lot is analyzed to confirm identity, purity, and the absence of metallic impurities. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with every shipment. We support customer audits and can provide material to meet the stringent requirements of the electronics and semiconductor industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. Due to its highly volatile and moisture-sensitive nature, containers must be kept sealed under an inert atmosphere (argon or nitrogen) and allowed to reach room temperature before opening to prevent condensation and decomposition.
