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 features two methoxy groups attached to the same carbon atom, creating a dimethyl acetal structure. With a molecular weight of 90.12 g/mol, it belongs to the class of flammable liquids and is classified as Flam. Liq. 2 under GHS regulations, requiring careful handling due to its fire hazard properties.

1,1-dimethoxyethane is a colorless liquid at room temperature with a characteristic ether-like odor. As an organic ether compound, it exhibits good solubility in organic solvents and limited water solubility due to its hydrophobic methoxy groups. The compound has a relatively low molecular weight of 90.12 g/mol and demonstrates typical ether properties including volatility and flammability, which contributes to its Flam. Liq. 2 classification.

1,1-dimethoxyethane is primarily used as a protecting group reagent in organic synthesis, particularly for aldehydes and ketones. It serves as an important intermediate in pharmaceutical manufacturing and fine chemical production. The compound is also employed as a solvent in various chemical reactions and as a starting material for the synthesis of other organic compounds. Its acetal structure makes it valuable in synthetic chemistry for temporary protection of carbonyl groups during multi-step reactions.

1,1-dimethoxyethane must be handled with appropriate fire safety precautions due to its Flam. Liq. 2 classification. Essential safety measures include wearing chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent vapor accumulation. Keep away from heat sources, sparks, and open flames. Use explosion-proof electrical equipment and ensure proper grounding to prevent static discharge during transfer operations.

1,1-dimethoxyethane should be stored in a cool, dry, well-ventilated area away from heat sources and ignition sources. Use appropriate fire-resistant storage cabinets designed for flammable liquids. Keep containers tightly sealed and protected from light to prevent degradation. Store away from strong acids and oxidizing agents to avoid incompatible reactions. Maintain storage temperatures below the substance's flash point and ensure proper fire suppression systems are available in storage areas.

In case of skin contact with 1,1-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 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms develop or persist after exposure.

1,1-dimethoxyethane must be disposed of as hazardous waste in accordance with local and national environmental regulations. The substance cannot be disposed of through regular waste streams due to its flammable nature. Contact licensed hazardous waste disposal companies for proper collection and treatment. Ensure containers are properly labeled and segregated from other waste types. Never dispose of down drains or into the environment, as this violates environmental protection laws and poses safety risks.

1,1-dimethoxyethane is classified under ADR Class 3 (flammable liquids), Packing Group II, indicating moderate danger level during transport. Transportation must comply with dangerous goods regulations, requiring appropriate packaging, labeling with GHS02 pictograms, and proper shipping documentation. Vehicles must be equipped with appropriate fire safety equipment and drivers must hold ADR certification. Packages must display the 'Danger' signal word and flammable liquid hazard symbols according to transport regulations.

1,1-dimethoxyethane is regulated under the CLP Regulation for classification and labeling as Flam. Liq. 2 with the GHS02 pictogram. It falls under REACH registration requirements for chemical substances in the European Union. The compound is not listed as a Substance of Very High Concern (SVHC), indicating lower regulatory restrictions compared to more hazardous chemicals. However, standard industrial chemical handling regulations and workplace safety requirements still apply for professional use.
