Description

Tetraethyllead (CAS NO 78-00-2) is a highly specialized organolead compound historically significant as a gasoline anti-knock additive. Its primary commercial value lies in its exceptional ability to increase fuel octane ratings, though its use is now heavily restricted globally. This chemical is of critical importance for industrial and research applications requiring precise organometallic synthesis, catalyst studies, and specialized chemical manufacturing. It is supplied to meet the stringent demands of advanced material science research and controlled industrial processes.

Application

• Historical Fuel Additive: Research and reference standard for the study of leaded gasoline and its environmental impact.
• Organometallic Synthesis: Acts as a key reagent or intermediate in the synthesis of other organolead compounds and complex metal-organic frameworks.
• Catalysis Research: Used in specialized catalytic processes and studies within controlled laboratory environments.
• Chemical Manufacturing: Employed in the production of specific industrial chemicals where lead alkylation is required.
• Analytical Standard: Serves as a high-purity reference material for environmental testing, forensic analysis, and regulatory compliance verification.

Quality Control

Our Tetraethyllead is manufactured and handled under strict controls to ensure batch-to-batch consistency and high purity for specialized applications. Quality is verified through a comprehensive suite of analytical techniques including gas chromatography (GC) and spectroscopic methods. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to ensure traceability and compliance with your research or process specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and toxic nature, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) when possible to prevent decomposition and moisture ingress. Store separately from strong oxidizers and acids.
