Magnesium benzene

Magnesium benzene is an organometallic compound with the molecular formula C12H10Mg and CAS number 555-54-4. This compound consists of a magnesium atom bonded to benzene rings, making it part of the organometallic chemistry family. With a molecular weight of 178.51 g/mol, it serves as an important reagent in organic synthesis and industrial applications requiring organometallic catalysts.

Magnesium benzene is a solid organometallic compound that typically appears as a crystalline material. As an organometallic substance, it is highly reactive with air and moisture, requiring inert atmosphere handling. The compound is generally insoluble in water but may dissolve in organic solvents under appropriate conditions. Its reactivity profile makes it sensitive to oxidation and hydrolysis.

Magnesium benzene is primarily used as a catalyst and reagent in organic synthesis reactions. It serves in metal-catalyzed coupling reactions, polymerization processes, and as a precursor for other organometallic compounds. The compound finds applications in pharmaceutical intermediate synthesis, specialty chemical manufacturing, and research laboratories requiring organometallic chemistry expertise for advanced synthetic transformations.

Magnesium benzene requires careful handling due to its organometallic nature and pyrophoric properties (ADR Class 4.2). Always wear appropriate PPE including chemical-resistant gloves, safety goggles, and protective clothing. Work under inert atmosphere (nitrogen or argon) to prevent oxidation. Ensure adequate ventilation and have appropriate fire suppression equipment available. Avoid contact with water, air, and oxidizing agents.

Magnesium benzene must be stored under inert atmosphere in tightly sealed containers to prevent air and moisture contact. Keep in a cool, dry location away from heat sources, oxidizing agents, and incompatible materials. Store in original packaging with proper labeling. Ensure storage area has appropriate fire suppression systems suitable for pyrophoric materials and maintain inventory records for regulatory compliance.

Magnesium benzene exposure requires immediate action due to its reactive nature. For skin contact, remove contaminated clothing and flush with copious amounts of water. In case of eye contact, rinse thoroughly with water for at least 15 minutes. If inhaled, move to fresh air immediately. Seek medical attention for any exposure. Do not use water on spilled material due to potential violent reaction.

Magnesium benzene disposal must follow hazardous waste regulations due to its pyrophoric classification. Contact licensed hazardous waste disposal companies experienced with organometallic compounds. Never dispose of in regular waste streams or pour down drains. Small quantities may be carefully deactivated by trained personnel using appropriate quenching agents under controlled conditions before disposal according to local environmental regulations.

Magnesium benzene is classified under ADR Class 4.2 (Spontaneously Combustible Substances), Packing Group I, indicating high danger level. Transport requires specialized packaging meeting UN specifications for pyrophoric materials. Vehicles must carry appropriate emergency equipment and documentation. Only trained personnel should handle transportation, and specific routing restrictions may apply depending on local regulations and quantities transported.

Magnesium benzene is regulated under various chemical safety frameworks including REACH registration requirements in Europe. While not classified as SVHC (Substance of Very High Concern), it remains subject to CLP classification and labeling regulations. Transportation is governed by ADR/RID regulations for dangerous goods. Users must comply with workplace safety regulations and may need specific permits depending on quantities and applications.
