1,1-dimethoxyethane

1,1-dimethoxyethane is an organic chemical compound with the molecular formula C4H10O2 and CAS number 534-15-6. This ether derivative has a molecular weight of 90.12 g/mol and belongs to the acetal family of compounds. It is classified as a flammable liquid category 2 under GHS regulations, requiring careful handling due to its fire hazard properties and volatility at ambient temperatures.

1,1-dimethoxyethane is a colorless liquid at room temperature with a characteristic ether-like odor. As an acetal compound, it exhibits good solubility in polar organic solvents and has moderate water solubility. The substance has a relatively low boiling point typical of ethers, making it volatile under standard conditions. Its chemical structure features two methoxy groups attached to the same carbon atom, contributing to its stability and solvent properties.

1,1-dimethoxyethane serves primarily as a chemical intermediate in organic synthesis and pharmaceutical manufacturing. It is commonly used as a protecting group for aldehydes and ketones in complex synthetic pathways. The compound also finds application as a specialty solvent in chemical reactions requiring anhydrous conditions. Additionally, it serves as a precursor in the production of various fine chemicals and pharmaceutical intermediates in industrial processes.

1,1-dimethoxyethane requires careful handling due to its flammable liquid category 2 classification. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and appropriate respiratory protection when necessary. Work should be conducted in well-ventilated areas or under fume hoods, away from ignition sources, heat, and open flames. Ground all equipment to prevent static electricity buildup, and ensure fire extinguishing equipment is readily available during handling operations.

1,1-dimethoxyethane must be stored in cool, dry, well-ventilated areas away from heat sources and ignition points. Use only approved containers and ensure proper grounding to prevent static discharge. Store separately from strong oxidizing agents and acids to prevent incompatible reactions. Maintain storage temperatures below the substance's flash point and implement appropriate fire suppression systems. Regular inspection of containers for leaks or deterioration is essential for safe storage practices.

Skin contact with 1,1-dimethoxyethane requires immediate removal of contaminated clothing and thorough washing with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15-20 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately and monitor breathing. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult safety data sheets for complete first aid procedures.

1,1-dimethoxyethane disposal must comply with local and national hazardous waste regulations as it is classified as flammable waste. The substance should never be discharged into drains, soil, or water bodies. Arrange disposal through licensed hazardous waste contractors who can handle flammable organic compounds safely. Consider waste minimization through recycling or recovery when possible. Maintain proper documentation of disposal activities as required by environmental regulations.

1,1-dimethoxyethane is classified under ADR as Class 3 (flammable liquids), Packing Group II for transportation purposes. This classification requires specific packaging, labeling, and documentation in accordance with dangerous goods regulations. Vehicles must display appropriate hazard placards and carry emergency response information. Only trained personnel should handle transportation, and specific routing restrictions may apply. Ensure compliance with international transport regulations for cross-border shipments.

1,1-dimethoxyethane is subject to standard chemical regulations including REACH registration requirements in Europe and CLP classification as a flammable liquid category 2. The substance is not currently listed as a Substance of Very High Concern (SVHC) under REACH. However, its flammable properties require compliance with workplace safety regulations and proper hazard communication through safety data sheets and appropriate labeling with GHS pictograms.
