1,1,3-trimethoxybutane is an organic chemical compound with the molecular formula C7H16O3 and CAS number 10138-89-3. This ether derivative features three methoxy groups attached to a butane backbone, resulting in a molecular weight of 148.2 g/mol. It belongs to the class of alkyl ethers and is characterized by its multiple ether linkages, which influence its chemical properties and industrial applications.

1,1,3-trimethoxybutane is a colorless to pale yellow liquid at room temperature with a characteristic ether-like odor. The compound exhibits moderate volatility due to its ether groups and has a density lower than water. It shows limited solubility in water but demonstrates good miscibility with organic solvents such as alcohols, ethers, and hydrocarbons, making it suitable for various solvent applications.

1,1,3-trimethoxybutane serves primarily as a specialty solvent in organic synthesis and chemical manufacturing processes. Its multiple ether groups make it valuable for dissolving various organic compounds and as a reaction medium. The compound finds applications in pharmaceutical intermediates synthesis, fine chemical production, and specialized coating formulations where its unique solvation properties are required.

1,1,3-trimethoxybutane should be handled with standard organic solvent precautions despite having no specific GHS classification. Use appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and work in well-ventilated areas or under fume hoods. Avoid contact with skin and eyes, prevent inhalation of vapors, and eliminate ignition sources as the compound is classified as flammable under ADR regulations.

1,1,3-trimethoxybutane must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers in secondary containment and away from incompatible materials such as strong oxidizers and acids. Store in approved flammable liquid storage areas following local fire safety regulations, maintaining temperatures below 25°C when possible to minimize vapor formation.

In case of skin contact with 1,1,3-trimethoxybutane, 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 and seek medical attention. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention.

1,1,3-trimethoxybutane must be disposed of as hazardous waste according to local and European waste regulations. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Never pour down drains, into soil, or mix with municipal waste. Small quantities can be incinerated in approved facilities equipped with appropriate emission controls. Always check local regulations and obtain proper waste classification codes before disposal.

1,1,3-trimethoxybutane is classified under ADR as Class 3 (Flammable Liquids), Packing Group III, requiring appropriate dangerous goods packaging and documentation. Use UN-approved containers and ensure proper labeling with flammable liquid placards. Transport vehicles must comply with ADR requirements including proper ventilation, fire extinguishers, and driver training certification. Follow all dangerous goods shipping documentation requirements for European transport.

1,1,3-trimethoxybutane is subject to standard REACH registration requirements for chemical substances manufactured or imported in the European Union above one tonne per year. The compound is not classified as an SVHC (Substance of Very High Concern) and has no specific CLP classification. Standard workplace exposure controls and chemical safety assessments apply according to European chemical legislation and local occupational health regulations.
