1,2-dimethoxyethane

1,2-dimethoxyethane is an organic chemical compound with the molecular formula C4H10O2 and CAS number 110-71-4. It belongs to the ether family and has a molecular weight of 90.12 g/mol. This substance is classified as a flammable liquid with reproductive toxicity and acute toxicity properties. It is commonly used as a solvent and chelating agent in various industrial applications due to its ability to coordinate with metal ions through its two oxygen atoms.

1,2-dimethoxyethane is a colorless liquid at room temperature with a characteristic ether-like odor. It has excellent solubility in water and most organic solvents due to its ether groups. The compound has a relatively low boiling point and high volatility. Its chemical structure, containing two methoxy groups attached to an ethane backbone, gives it unique chelating properties that make it valuable as a coordinating solvent for organometallic reactions and metal complexes.

1,2-dimethoxyethane is primarily used as a coordinating solvent in organometallic chemistry and lithium battery electrolytes. It serves as an excellent medium for Grignard reactions and other organometallic syntheses due to its ability to stabilize metal ions. The compound is also employed in polymer chemistry, pharmaceutical synthesis, and as a reaction medium for various chemical processes. Its chelating properties make it particularly valuable in applications requiring metal ion coordination and stabilization.

1,2-dimethoxyethane requires careful handling due to its flammable, reproductive toxic, and acutely toxic properties. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume hoods to prevent vapor inhalation. Keep away from ignition sources, heat, and sparks. Avoid skin contact and inhalation. Pregnant women should avoid exposure due to reproductive toxicity concerns. Ensure proper grounding of equipment to prevent static discharge.

1,2-dimethoxyethane should be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Keep containers tightly closed and store in original packaging. Maintain storage temperature below 25°C and protect from direct sunlight. Store separately from oxidizing agents, acids, and incompatible materials. Ensure adequate fire prevention measures and emergency equipment are available. Check containers regularly for leaks or damage, and maintain proper inventory records for regulatory compliance.

In case of skin contact with 1,2-dimethoxyethane, immediately remove contaminated clothing and wash the affected area with plenty of soap and water for at least 15 minutes. If inhaled, move the person to fresh air immediately and seek medical attention if breathing difficulties occur. In case of eye contact, rinse thoroughly with water for at least 15 minutes and remove contact lenses if present. If ingested, do not induce vomiting and seek immediate medical attention. Always consult a physician in case of exposure.

1,2-dimethoxyethane must be disposed of as hazardous waste according to local, national, and international regulations. Never pour down drains, into soil, or release into the environment. Contact licensed waste disposal companies for proper collection and treatment. Small quantities may be suitable for incineration at authorized facilities with appropriate emission controls. Maintain proper documentation of waste disposal activities. Consider recovery or recycling options where technically and economically feasible to minimize environmental impact.

1,2-dimethoxyethane is classified as ADR Class 3 (flammable liquid) Packing Group II for transportation purposes. It must be shipped in appropriate UN-specification packaging with proper labeling including GHS02, GHS07, and GHS08 pictograms. Transport vehicles must comply with ADR regulations for flammable liquids. Proper shipping documentation, including safety data sheets, must accompany shipments. Only authorized carriers experienced in handling hazardous materials should transport this substance. Emergency response information must be readily available during transport.

1,2-dimethoxyethane is subject to various European regulations including REACH registration requirements and CLP classification as Flam. Liq. 2, Repr. 1B, and Acute Tox. 4. While not currently listed as a SVHC, it requires safety data sheets and appropriate hazard labeling with the "Danger" signal word. Users must comply with occupational exposure limits and workplace safety regulations. Industrial users may need to implement risk management measures and report usage under REACH. Regular monitoring of regulatory updates is recommended.
