2-Methylpentane (107-83-5) is a colourless liquid;Its general description watery liquid with a gasoline-like odor, floats on water. Produces an irritating vapor. In Air & Water its reactions highly flammable. Reactivity profile saturated aliphatic hydrocarbons, such as Isohexene , may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. Health Hazard Inhalation causes irritation of respiratory tract, cough, mild depression, cardiac arrhythmias. Aspiration causes severe lung irritation, coughing, pulmonary edema; excitement followed by depression. Ingestion causes nausea, vomiting, swelling of abdomen, headache, depression.
