2,6-dimethylheptan-4-one

2,6-dimethylheptan-4-one is an organic ketone compound with the molecular formula C9H18O and CAS number 108-83-8. It features a seven-carbon chain with methyl substituents at positions 2 and 6, and a ketone functional group at position 4. With a molecular weight of 142.24 g/mol, this branched aliphatic ketone is classified as a flammable liquid and exhibits moderate hazard properties requiring appropriate handling precautions.

2,6-dimethylheptan-4-one is a colorless to pale yellow liquid at room temperature with a characteristic ketone odor. As a moderately polar organic compound, it shows limited solubility in water but good solubility in most organic solvents such as alcohols, ethers, and hydrocarbons. The branched structure influences its boiling point and volatility compared to linear ketones of similar molecular weight, making it suitable for various industrial applications.

2,6-dimethylheptan-4-one is primarily used as a solvent in industrial applications and as an intermediate in organic synthesis. Its ketone functionality makes it valuable for chemical reactions including condensations, reductions, and as a building block for more complex molecules. It may also find applications in formulation chemistry, cleaning products, and as a processing aid in various manufacturing operations where a medium-polarity solvent is required.

2,6-dimethylheptan-4-one must be handled with appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Work in well-ventilated areas or under fume extraction to avoid inhalation of vapors. Keep away from ignition sources, heat, and open flames due to its flammable nature (Flam. Liq. 3). Avoid skin and eye contact, and ensure emergency washing facilities are readily available during handling operations.

2,6-dimethylheptan-4-one should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition. Keep containers grounded and bonded during transfer operations. Store away from incompatible materials such as strong oxidizing agents and bases. Ensure storage areas comply with local fire safety regulations for flammable liquids and maintain temperatures below flash point to prevent vapor accumulation.

In case of skin contact with 2,6-dimethylheptan-4-one, immediately wash the affected area with plenty of water and soap, removing contaminated clothing. For eye contact, flush immediately with water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. If swallowed, do not induce vomiting and seek immediate medical attention. Always consult the safety data sheet for complete first aid procedures and contact emergency services if symptoms persist.

2,6-dimethylheptan-4-one must be disposed of according to local, national, and EU waste regulations as hazardous chemical waste. Do not discharge into drains, waterways, or soil. Contact licensed waste disposal contractors for collection and treatment. Empty containers should be handled as hazardous waste unless properly cleaned. Consider recovery or recycling options where economically viable, and maintain proper waste documentation as required by applicable environmental legislation.

2,6-dimethylheptan-4-one is classified under ADR as Class 3 (flammable liquids), Packing Group III for transportation. It requires appropriate UN-specification packaging and labeling with flammable liquid hazard markings. Transport vehicles must comply with ADR regulations including appropriate equipment and driver training. Shipping documentation must include proper shipping names, hazard classes, and emergency response information. Ensure carriers are certified for hazardous materials transport.

2,6-dimethylheptan-4-one is subject to REACH regulation requiring registration for manufacture or import above one tonne per year in the EU. It falls under CLP regulation for classification and labeling as Flam. Liq. 3 and STOT SE 3. The substance is not currently listed as SVHC (Substance of Very High Concern). Users must comply with occupational exposure limits, transport regulations (ADR), and local environmental discharge restrictions where applicable.
