1,2-dimethoxyethane

1,2-dimethoxyethane is an organic solvent with the molecular formula C4H10O2 and CAS number 110-71-4. This ether compound has a molecular weight of 90.12 g/mol and belongs to the glycol ether family. It is classified as a flammable liquid with reproductive toxicity and acute toxicity properties. The substance is widely used in industrial applications due to its excellent solvating properties and ability to form complexes with metal ions.

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 structure. The compound is highly volatile and has a relatively low boiling point. Its chemical structure consists of an ethylene glycol backbone with both hydroxyl groups replaced by methoxy groups, giving it unique chelating properties that make it valuable as a coordinating solvent.

1,2-dimethoxyethane is primarily used as a polar aprotic solvent in organic synthesis and electrochemistry. It serves as an excellent medium for organometallic reactions, particularly those involving lithium and magnesium compounds. The substance is also employed in battery electrolytes, polymer synthesis, and as a chelating agent in coordination chemistry. Its ability to dissolve both organic and inorganic compounds makes it valuable in pharmaceutical manufacturing and advanced chemical processes.

1,2-dimethoxyethane requires careful handling due to its flammable and 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 inhalation exposure. Keep away from ignition sources, heat, and open flames. Use grounded equipment to prevent static discharge. Avoid skin and eye contact, and never eat, drink, or smoke when handling this substance.

1,2-dimethoxyethane must be stored in a cool, dry, well-ventilated area away from heat sources and ignition points. Keep containers tightly closed and store in original packaging or compatible containers. The substance should be segregated from strong oxidizing agents, acids, and bases. Store below 25°C and protect from direct sunlight. Ensure proper grounding of storage containers and maintain appropriate fire suppression systems in storage areas due to its flammable nature.

In case of skin contact with 1,2-dimethoxyethane, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air and keep them at rest. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician after any significant exposure.

1,2-dimethoxyethane must be disposed of as hazardous waste in accordance with local, national, and EU regulations. Never pour down drains or dispose of with regular waste. The substance requires specialized treatment at authorized waste disposal facilities. Container residues should also be treated as hazardous waste. Consult your local waste management authority for specific disposal requirements and approved disposal facilities. Keep proper documentation of waste disposal for regulatory compliance.

1,2-dimethoxyethane is classified under ADR Class 3 (flammable liquids), Packing Group II, indicating moderate danger level. Transportation requires proper packaging in UN-approved containers with appropriate labeling including GHS02, GHS07, and GHS08 pictograms. Vehicles must carry appropriate safety equipment and drivers need ADR certification. The substance requires proper documentation including transport documents and emergency response information. Ensure compliance with all applicable transportation regulations for dangerous goods.

1,2-dimethoxyethane is subject to comprehensive EU chemical regulations including REACH and CLP classification. The substance is classified as Flam. Liq. 2, Repr. 1B, and Acute Tox. 4, requiring specific labeling with danger signal word and appropriate pictograms. While not currently listed as SVHC, its reproductive toxicity classification means it may face restrictions in consumer applications. Companies must comply with registration, notification, and safety data sheet requirements under REACH and CLP regulations.
