Tetraethyllead
Tetraethyllead (CAS 78-00-2), with the linear formula (C2H5)4Pb and a molecular weight of 323.44 g/mol, is an organometallic compound. Historically recognised for its use as a gasoline additive to boost octane ratings and prevent engine knocking, its applications are now highly restricted due to toxicity. It is supplied by TSS as a high-purity reagent for specialised chemical synthesis and research.
Historical Fuel Additive
Tetraethyllead was extensively used as an anti-knock agent in petrol, significantly increasing octane ratings and improving engine performance. This application has been phased out in most parts of the world due to severe environmental and health concerns.
Chemical Synthesis
As an organolead compound, Tetraethyllead can serve as a precursor or reagent in specific organic synthesis pathways. Its reactivity allows for the introduction of ethyl groups or lead into various chemical structures for research purposes.
Research and Development
Tetraethyllead is utilised in laboratory settings for research into organometallic chemistry. Studies may explore its reaction mechanisms, decomposition pathways, or its potential in niche catalytic applications under strictly controlled conditions.

What is Tetraethyllead used for?
+
Tetraethyllead was historically used as an additive in gasoline to increase octane ratings and prevent engine knocking. It is now primarily used in specialised chemical synthesis and research due to its toxicity.
What is the CAS number and formula for Tetraethyllead?
+
The CAS number for Tetraethyllead is 78-00-2, and its linear formula is (C2H5)4Pb.
What grade and purity does Tech Serve Solutions supply?
+
Tech Serve Solutions supplies Tetraethyllead with an assay of ≥99.99%. TSS does not represent this product as USP, BP, EP, or any other pharmacopoeia grade.
How should Tetraethyllead be handled safely?
+
Tetraethyllead is highly toxic and dangerous. Handling requires extreme caution, including the use of appropriate personal protective equipment such as eyeshields, face shields, gloves, and a full-face or combination respirator with ABEK filter cartridges. It is acutely toxic if swallowed, in contact with skin, or if inhaled, and can cause serious damage to organs through prolonged exposure. It is also very toxic to aquatic life with long-lasting effects.
Is Tetraethyllead a controlled substance?
+
While not explicitly listed as a scheduled controlled substance in all jurisdictions, Tetraethyllead is a highly regulated chemical due to its extreme toxicity and historical environmental impact. Its sale, use, and transport are subject to strict national and international regulations.
How is Tetraethyllead packed and shipped?
+
Tetraethyllead is packed and shipped according to stringent international regulations for hazardous materials (UN 1649, Class 6.1). TSS ensures compliance with all transport and export requirements for this dangerous substance.
