5-methylhexan-2-one

5-methylhexan-2-one is an organic ketone compound with the molecular formula C7H14O and CAS number 110-12-3. This chemical features a seven-carbon chain with a ketone functional group at the second position and a methyl branch at the fifth carbon. With a molecular weight of 114.19 g/mol, it belongs to the family of aliphatic ketones and exhibits flammable properties, requiring careful handling in industrial applications.

5-methylhexan-2-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 readily dissolves in most organic solvents including alcohols, ethers, and hydrocarbons. The compound has a boiling point in the range typical for medium-chain ketones and exhibits moderate volatility under standard conditions.

5-methylhexan-2-one serves primarily as an intermediate in organic synthesis and as a solvent in various industrial processes. It finds applications in the production of pharmaceuticals, agrochemicals, and specialty chemicals where its ketone functionality enables further chemical transformations. The compound is also utilized in formulation chemistry for coatings, adhesives, and cleaning products due to its solvent properties and moderate volatility characteristics.

5-methylhexan-2-one requires careful handling due to its flammable nature and acute toxicity classification. Workers must wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation to prevent vapor accumulation, eliminate ignition sources, and avoid skin and eye contact. Work in well-ventilated areas or under fume hoods, and have emergency equipment readily available.

5-methylhexan-2-one must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames due to its Class 3 flammable liquid classification. Use appropriate containers made of compatible materials and ensure proper labeling with GHS pictograms. Keep away from oxidizing agents and incompatible materials, maintain storage temperatures below recommended limits, and implement proper fire prevention measures in storage areas.

5-methylhexan-2-one exposure requires immediate action depending on the contact route. For skin contact, remove contaminated clothing and wash thoroughly with soap and water. In case of eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical care while providing the safety data sheet to medical personnel.

5-methylhexan-2-one disposal must comply with local and national hazardous waste regulations due to its flammable and toxic properties. The substance should be collected in appropriate containers and transferred to authorized waste treatment facilities for proper incineration or chemical treatment. Never dispose of in regular drains, soil, or municipal waste streams. Consult local environmental authorities and waste management companies for specific disposal requirements and procedures.

5-methylhexan-2-one is classified as ADR Class 3, Packing Group III for transportation, identifying it as a flammable liquid with relatively lower risk. Transport requires appropriate UN-approved packaging, proper labeling with Class 3 hazard diamonds, and compliance with ADR regulations. Vehicles must carry appropriate fire extinguishing equipment, and drivers need hazardous materials training. Ensure proper documentation including transport documents and emergency response information accompanies shipments.

5-methylhexan-2-one is subject to European REACH regulation requiring registration for commercial use and CLP regulation for classification and labeling as Flam. Liq. 3 and Acute Tox. 4. The substance is not currently listed as an SVHC (Substance of Very High Concern) under REACH. Companies must ensure compliance with workplace exposure limits, proper safety data sheet provision, and appropriate risk assessment procedures for occupational use.
