2,3-dimethylbutane

2,3-dimethylbutane is a branched-chain alkane hydrocarbon with the molecular formula C6H14 and CAS number 79-29-8. It belongs to the family of saturated aliphatic hydrocarbons and has a molecular weight of 86.18 g/mol. This isomer of hexane features two methyl groups attached to the second and third carbon atoms of a butane backbone, making it a highly flammable liquid classified as dangerous goods under transportation regulations.

2,3-dimethylbutane is a colorless liquid at room temperature with characteristic hydrocarbon odor. As a nonpolar alkane, it exhibits very low water solubility but readily dissolves in organic solvents such as alcohols, ethers, and other hydrocarbons. The compound has a relatively low boiling point typical of branched alkanes and high volatility, contributing to its flammable nature and vapor formation at ambient conditions.

2,3-dimethylbutane serves primarily as a specialty solvent in chemical synthesis and analytical applications. It is utilized in organic chemistry research, pharmaceutical intermediate production, and as a reference standard in gas chromatography. The compound also finds use in specialized cleaning formulations and as a component in hydrocarbon mixtures for specific industrial processes requiring precise solvent characteristics and controlled volatility properties.

2,3-dimethylbutane requires careful handling due to its flammable and potentially harmful properties. Use appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation to prevent vapor accumulation and avoid all ignition sources. Handle in well-ventilated areas away from heat, sparks, and open flames. Avoid skin contact as it may cause irritation, and prevent inhalation of vapors which can affect the central nervous system.

2,3-dimethylbutane must be stored in a cool, dry, well-ventilated area away from heat sources and ignition points. Use appropriate containers designed for flammable liquids, ensuring they are properly sealed and grounded. Store separately from oxidizing agents and incompatible materials. Maintain storage temperature below flash point and implement proper fire prevention measures including explosion-proof electrical equipment and adequate fire suppression systems in storage areas.

Immediate first aid measures depend on the exposure route. For skin contact, remove contaminated clothing and wash thoroughly with soap and water. In case of eye contact, rinse immediately with plenty of clean water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention if breathing difficulties occur. If swallowed, do not induce vomiting and seek immediate medical attention due to aspiration toxicity risks.

2,3-dimethylbutane disposal must comply with local and European waste regulations as hazardous waste. Contact licensed waste disposal companies specialized in flammable organic solvents. Do not dispose of down drains or in regular waste streams due to environmental and flammability concerns. Consider recovery and recycling options where feasible. Ensure proper waste classification and documentation according to applicable waste codes and transport the material using authorized hazardous waste carriers only.

2,3-dimethylbutane is classified under ADR Class 3 (flammable liquids) Packing Group II, requiring specialized dangerous goods transport procedures. Use UN-approved packaging suitable for flammable liquids and ensure proper labeling with appropriate hazard placards. Transport must be conducted by ADR-certified carriers with trained personnel. Vehicles must be equipped with appropriate safety equipment and follow designated routes for dangerous goods transportation throughout Europe.

2,3-dimethylbutane is subject to various European chemical regulations including REACH registration requirements and CLP classification obligations. It is not currently listed as a Substance of Very High Concern (SVHC). Companies must comply with safety data sheet provisions, workplace exposure limits, and proper hazard communication. Industrial users must implement appropriate risk management measures and may need to fulfill downstream user obligations under REACH depending on use patterns and quantities.
