Magnesium ethane

Magnesium ethane is an organometallic compound with the molecular formula C4H10Mg and CAS number 557-18-6. This substance belongs to the family of organomagnesium compounds, featuring magnesium atoms bonded to organic ethyl groups. With a molecular weight of 82.43 g/mol, it is classified as a highly hazardous chemical due to its pyrophoric and water-reactive properties. It poses significant safety risks including spontaneous ignition and corrosive effects on skin.

Magnesium ethane is a pyrophoric liquid that ignites spontaneously upon contact with air. It reacts violently with water, releasing flammable gases and heat. The compound is highly sensitive to moisture and oxygen, requiring inert atmosphere handling. Due to its organometallic nature, it is typically stored and handled under nitrogen or argon. The substance exhibits corrosive properties and can cause severe chemical burns upon contact with skin or mucous membranes.

Magnesium ethane is primarily used as a reagent in organic synthesis and as a precursor for various organomagnesium compounds. It serves applications in pharmaceutical intermediate synthesis, polymer chemistry, and specialized chemical manufacturing processes. The compound is utilized in research laboratories for organometallic chemistry studies and catalysis development. Its reactive nature makes it valuable for creating carbon-magnesium bonds in synthetic organic chemistry, particularly in advanced pharmaceutical and fine chemical production.

Magnesium ethane requires strict safety protocols including use of appropriate personal protective equipment: chemical-resistant gloves, safety goggles, and protective clothing. Work must be conducted under inert atmosphere in well-ventilated areas or fume hoods. Avoid contact with water, moisture, and air to prevent violent reactions. Keep fire extinguishing equipment nearby but avoid water-based extinguishers. Personnel should be trained in handling pyrophoric and corrosive materials before working with this substance.

Magnesium ethane must be stored under inert atmosphere (nitrogen or argon) in tightly sealed, moisture-proof containers. Storage areas should be cool, dry, and well-ventilated, away from heat sources, ignition sources, and incompatible materials. Keep separated from water, alcohols, acids, and oxidizing agents. Storage facilities should have appropriate fire suppression systems (excluding water-based systems) and emergency response equipment. Regular inspection of container integrity is essential to prevent exposure to air or moisture.

Immediate action is required upon contact with magnesium ethane. For skin contact, remove contaminated clothing and flush affected area with copious amounts of water for at least 15 minutes, then seek immediate medical attention. In case of eye contact, rinse thoroughly with water and get emergency medical care. If inhaled, move to fresh air immediately. For spills, evacuate the area, eliminate ignition sources, and contain using dry sand or inert absorbent materials. Never use water on spills.

Magnesium ethane disposal requires specialized hazardous waste procedures due to its pyrophoric and corrosive properties. The substance must be neutralized carefully under controlled conditions by qualified personnel using appropriate quenching agents in inert atmosphere. Disposal should be conducted through licensed hazardous waste contractors familiar with organometallic compounds. All containers and contaminated materials require proper classification and handling according to local and European waste regulations. Never dispose of in regular waste streams or sewers.

Magnesium ethane is classified under ADR Class 4.2 (substances liable to spontaneous combustion), Packing Group I, indicating highest danger level. Transport requires specialized packaging designed for pyrophoric liquids, with proper labeling including GHS02 and GHS05 pictograms and 'Danger' signal word. Vehicles must comply with ADR regulations for Class 4.2 materials, including appropriate fire suppression systems and trained drivers. Shipping documentation must include proper shipping names, hazard classifications, and emergency response information.

Magnesium ethane is subject to comprehensive European chemical regulations including REACH registration requirements and CLP classification as Pyrophoric Liquid Category 1, Water-reactive Category 1, and Skin Corrosive Category 1B. It requires safety data sheets compliant with current regulations and appropriate hazard labeling. The substance is not currently listed as SVHC (Substance of Very High Concern). Industrial users must implement appropriate risk management measures and may require authorization depending on use patterns and quantities handled.

Magnesium ethane is available through OYSI, a specialized European distributor of technical chemicals with expertise in hazardous and specialty compounds. As an established chemical supplier, OYSI provides proper documentation, safety data sheets, and regulatory compliance support for organometallic compounds. Due to the specialized nature and safety requirements of magnesium ethane, procurement should only be through qualified distributors who understand the handling, storage, and transportation requirements of pyrophoric materials.
