Heptan-2-one

Heptan-2-one is an organic ketone compound with the molecular formula C7H14O and CAS number 110-43-0. It is a seven-carbon chain ketone with the carbonyl group located at the second carbon position. With a molecular weight of 114.19 g/mol, this chemical belongs to the methyl ketone family and is classified as a flammable liquid with moderate toxicity warnings under GHS classification systems.

Heptan-2-one is a colorless liquid with a characteristic fruity, banana-like odor typical of ketones. It has limited solubility in water but is miscible with most organic solvents including alcohols, ethers, and hydrocarbons. The compound exhibits moderate volatility at room temperature and has a relatively low flash point, contributing to its flammable liquid classification under safety regulations.

Heptan-2-one is primarily used as an industrial solvent in paint thinners, lacquers, and coating formulations due to its excellent dissolving properties. It serves as an intermediate in organic synthesis for pharmaceutical and fine chemical manufacturing. The compound is also utilized in the production of flavoring agents and fragrances, where its fruity odor profile makes it valuable for creating specific scent compositions in commercial applications.

Heptan-2-one requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection when ventilation is inadequate. Work should be conducted in well-ventilated areas or under fume hoods to prevent vapor accumulation. Avoid contact with skin, eyes, and inhalation of vapors. Keep away from ignition sources, heat, and open flames due to its flammable nature (Flam. Liq. 3 classification).

Heptan-2-one should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Storage areas must be equipped with appropriate fire suppression systems due to its flammable liquid classification. Keep containers grounded during transfer operations and store away from incompatible materials such as strong oxidizing agents, acids, and bases to prevent dangerous reactions.

In case of skin contact with heptan-2-one, 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 plenty of clean water for 15 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical attention if respiratory irritation occurs. In case of ingestion, do not induce vomiting and seek immediate medical assistance.

Heptan-2-one disposal must comply with local, national, and EU waste regulations as it is classified as hazardous waste. The substance should be collected in appropriate containers and disposed of through licensed hazardous waste disposal facilities. Incineration at high temperatures in approved facilities is typically the preferred method. Small quantities may be absorbed onto suitable absorbent materials before disposal, but dilution or discharge to sewers is prohibited under environmental regulations.

Heptan-2-one is classified under ADR regulations as Class 3 (flammable liquids), Packing Group III, requiring specific packaging and labeling requirements for transport. Containers must be properly sealed, labeled with appropriate hazard diamonds (GHS02, GHS07), and accompanied by proper shipping documentation. Transport vehicles must comply with ADR requirements for flammable liquids, including appropriate fire extinguishing equipment and driver training certification.

Heptan-2-one is subject to EU REACH regulation requiring registration for manufacture or import above specified tonnages. It falls under CLP regulation with mandatory hazard classification (Flam. Liq. 3; Acute Tox. 4) and appropriate labeling with Warning signal word. The substance is not currently listed as a SVHC (Substance of Very High Concern) but users must comply with occupational exposure limits and safety data sheet requirements for workplace use.
