1,1-diethoxyethane is an organic chemical compound with the molecular formula C6H14O2 and CAS number 105-57-7. It belongs to the acetal family, featuring two ethoxy groups attached to the same carbon atom. With a molecular weight of 118.17 g/mol, this compound is classified as a flammable liquid with irritant properties for skin and eyes, making it a regulated chemical requiring proper handling procedures.

1,1-diethoxyethane is a colorless liquid with a characteristic ether-like odor at room temperature. As an acetal compound, it exhibits moderate volatility and is soluble in organic solvents while having limited water solubility. The compound has a relatively low molecular weight of 118.17 g/mol and demonstrates typical properties of ethyl acetals, including sensitivity to acidic conditions and moderate boiling point.

1,1-diethoxyethane serves primarily as a chemical intermediate in organic synthesis and pharmaceutical manufacturing. It functions as a protecting group for aldehydes in synthetic chemistry, allowing selective reactions on other functional groups. The compound is also utilized in the production of fine chemicals, fragrances, and specialty solvents. Its acetal structure makes it valuable in multi-step organic syntheses where temporary protection of carbonyl groups is required.

1,1-diethoxyethane requires careful handling due to its flammable nature and irritant properties. Wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation and eliminate ignition sources as it's classified as Flam. Liq. 2. Avoid direct skin and eye contact due to its Skin Irrit. 2 and Eye Irrit. 2 classifications. Work in well-ventilated areas or under fume hoods.

1,1-diethoxyethane should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition sources. Keep containers in upright position and protect from direct sunlight and temperature fluctuations. Due to its flammable nature, store in appropriate flammable liquid storage cabinets. Avoid storage near incompatible materials such as strong acids, which can cause decomposition of the acetal structure.

Skin contact with 1,1-diethoxyethane 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 and remove contact lenses if present. If inhaled, move to fresh air immediately. Seek medical attention if irritation persists or symptoms develop, as the compound can cause skin and eye irritation.

1,1-diethoxyethane waste must be disposed of according to local and national hazardous waste regulations due to its flammable and irritant properties. Contact licensed hazardous waste disposal companies for collection and treatment. Never dispose of this chemical down drains or in regular waste streams. Small quantities may be suitable for controlled incineration at appropriate facilities. Always consult local environmental authorities for specific disposal requirements in your region.

1,1-diethoxyethane is classified under ADR Class 3 (flammable liquids), Packing Group II, requiring specific transport regulations compliance. Use appropriate UN-specification packaging designed for flammable liquids and ensure proper labeling with GHS02 and GHS07 pictogrammes. Transport vehicles must comply with ADR requirements for Class 3 substances. Ensure proper documentation including safety data sheets and transport emergency cards accompany shipments.

1,1-diethoxyethane is regulated under the CLP Regulation with classifications as Flam. Liq. 2, Skin Irrit. 2, and Eye Irrit. 2, requiring appropriate hazard labeling. It falls under REACH registration requirements for commercial use in the EU. The compound is not currently listed as a SVHC (Substance of Very High Concern). Users must comply with workplace safety regulations and provide appropriate risk assessments and safety measures for handling.
