Heptane

Description:

Heptane is a straight-chain alkane with the molecular formula C7H16, characterized by its seven carbon atoms and corresponding hydrogen atoms. It is a colorless, flammable liquid at room temperature, with a distinctive odor reminiscent of gasoline. Heptane is insoluble in water but soluble in organic solvents, making it useful in various applications, including as a non-polar solvent in laboratories and as a reference standard in octane rating tests for fuels. Its boiling point is relatively low compared to larger alkanes, and it exhibits a high vapor pressure, contributing to its volatility. Heptane is classified as a hydrocarbon and is part of the alkane series, which are saturated compounds with single bonds between carbon atoms. Due to its flammability, it must be handled with care, and it poses health risks if inhaled or ingested. In terms of reactivity, heptane undergoes typical alkane reactions, such as combustion, producing carbon dioxide and water. Its CAS number, 142-82-5, is a unique identifier used for regulatory and safety purposes.
