Tetramethylplumbane

Tetramethylplumbane is an organolead compound with the molecular 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 tetraalkylplumbanes. It is classified as an extremely hazardous material with multiple health and environmental risks, including reproductive toxicity, acute toxicity, and aquatic toxicity. Due to its lead content, it poses severe health risks and requires specialized handling procedures.

Tetramethylplumbane is an organometallic compound that typically exists as a colorless liquid at room temperature. As a lead-containing organic compound, it exhibits high volatility and can readily evaporate. The substance has limited solubility in water but is generally soluble in organic solvents. Its molecular structure consists of a central lead atom bonded to four methyl groups, giving it its characteristic properties and high toxicity profile.

Tetramethylplumbane serves primarily as a specialized reagent in advanced chemical synthesis and research applications. It may be used in organometallic chemistry for specific reactions requiring lead-containing compounds. However, due to its extreme toxicity and environmental hazards, its applications are highly restricted and limited to specialized industrial processes under strict safety controls. Most commercial uses have been phased out due to health and environmental concerns.

Tetramethylplumbane requires maximum safety precautions during handling due to its extreme toxicity. Personnel must wear full protective equipment including chemical-resistant gloves, protective clothing, and respiratory protection. Work should only be conducted in well-ventilated areas or fume hoods. Avoid all contact with skin, eyes, and inhalation of vapors. Only trained personnel should handle this substance, and emergency procedures must be readily available.

Tetramethylplumbane must be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. The storage area should be secured and accessible only to authorized personnel. Containers must be properly sealed and labeled according to GHS requirements with appropriate danger pictogrammes (GHS06, GHS08, GHS09). Storage facilities should have appropriate spill containment measures and emergency response equipment readily available.

Tetramethylplumbane exposure requires immediate emergency action. In case of skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water. For eye contact, flush immediately with water for at least 15 minutes. If inhaled, move the person to fresh air immediately. For ingestion, do not induce vomiting. Seek immediate medical attention in all cases of exposure and provide the safety data sheet to medical personnel.

Tetramethylplumbane disposal must comply with strict hazardous waste regulations due to its lead content and extreme toxicity. The substance cannot be disposed of through normal waste streams and requires specialized hazardous waste treatment. Disposal must be performed by licensed hazardous waste contractors following local and European waste regulations. Empty containers should also be treated as hazardous waste and disposed of through appropriate channels.

Tetramethylplumbane is classified under ADR Class 6.1 (Toxic substances), Packing Group I, indicating its extreme toxicity. Transportation requires specialized packaging meeting UN specifications and proper hazardous goods documentation. Vehicles must display appropriate hazard placards and emergency information. Only trained drivers with hazardous materials certification can transport this substance. Emergency response procedures must be available during transport.

Tetramethylplumbane is subject to extensive regulatory control under European legislation including REACH and CLP regulations. Its classification as Repr. 1A, Acute Tox. 1-2, STOT RE 2, and aquatic toxicity categories places it under strict regulatory oversight. The substance may be subject to authorization requirements, use restrictions, and mandatory risk management measures. Companies must comply with registration, notification, and safety data sheet requirements.

Tetramethylplumbane is available through OYSI, a specialized European distributor of technical chemicals. As a highly regulated substance with extreme toxicity, procurement requires proper authorization and compliance with regulatory requirements. OYSI ensures full regulatory compliance and provides appropriate documentation for legal purchase and use. Customers must demonstrate legitimate use and proper safety measures before procurement can be authorized.
