Tetramethylplumbane

Tetramethylplumbane is an organolead compound with the chemical formula C4H12Pb and CAS number 75-74-1. This chemical substance has a molecular weight of 267 g/mol and belongs to the family of alkyl lead compounds. It is classified as extremely hazardous due to its high toxicity and reproductive toxicity properties, requiring strict safety measures for handling and use.

Tetramethylplumbane is an organometallic compound that typically appears as a colorless liquid at room temperature. As an alkyl lead derivative, it exhibits high volatility and can readily evaporate. The compound is relatively unstable when exposed to air and light, potentially decomposing over time. Its physical properties make it particularly hazardous due to potential inhalation exposure through vapor formation.

Tetramethylplumbane is primarily used in specialized research applications and as a precursor in organometallic synthesis. Historically, organolead compounds were used in gasoline as anti-knock agents, but such applications have been largely discontinued due to environmental and health concerns. Today, its use is extremely limited and restricted to specific industrial processes under strict regulatory control.

Tetramethylplumbane requires extreme safety precautions due to its acute toxicity classification (Acute Tox. 1 and 2). Essential protective equipment includes chemical-resistant gloves, full face protection, and appropriate respiratory protection. Work must be conducted in well-ventilated areas or under fume hoods. Avoid skin contact, inhalation, and ingestion completely. Emergency procedures should be readily available, and only trained personnel should handle this substance.

Tetramethylplumbane must be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Use appropriate secondary containment and ensure containers are tightly sealed to prevent vapor release. Storage areas should be restricted to authorized personnel only and equipped with appropriate emergency equipment. Keep away from incompatible materials and ensure proper labeling with GHS pictograms GHS06, GHS08, and GHS09.

Tetramethylplumbane exposure requires immediate emergency response due to its extreme toxicity. In case of skin contact, remove contaminated clothing and rinse thoroughly with water for at least 15 minutes. For eye contact, flush immediately with water and seek medical attention. If inhaled, move to fresh air immediately and seek urgent medical care. Any exposure should be treated as a medical emergency requiring professional intervention.

Tetramethylplumbane disposal must comply with strict hazardous waste regulations due to its high toxicity and environmental impact. The substance cannot be disposed of through normal waste streams and requires specialized hazardous waste treatment facilities. Contact licensed waste management companies experienced in handling toxic organometallic compounds. Ensure proper documentation and follow all local, national, and European waste disposal regulations.

Tetramethylplumbane is classified under ADR Class 6.1 (toxic substances) with Packing Group I, indicating maximum danger level. Transportation requires specialized packaging meeting UN specifications and proper hazardous goods documentation. Only certified carriers experienced in handling highly toxic materials should transport this substance. Shipments must include appropriate emergency response information and comply with all dangerous goods transport regulations.

Tetramethylplumbane is subject to extensive regulatory control under European chemical legislation including REACH and CLP regulations. Its classification as Repr. 1A and multiple acute toxicity categories triggers strict handling requirements. The substance may face restrictions or authorization requirements for certain uses. Companies must ensure full compliance with notification, classification, and safety data sheet requirements before any commercial use.

Tetramethylplumbane is available through specialized chemical distributors like OYSI, which supplies industrial chemicals across Europe. Due to its extreme hazard classification and regulatory restrictions, procurement requires proper authorization and compliance documentation. Buyers must demonstrate legitimate use, appropriate safety measures, and regulatory compliance.
