3,5-Dimethylheptane

Description:
3,5-Dimethylheptane is an organic compound classified as an alkane, specifically a branched-chain hydrocarbon. Its molecular formula is C9H20, indicating it consists of nine carbon atoms and twenty hydrogen atoms. This compound features two methyl groups attached to the heptane backbone at the 3 and 5 positions, which contributes to its branched structure. 3,5-Dimethylheptane is a colorless liquid at room temperature and is typically insoluble in water due to its nonpolar nature, but it is soluble in organic solvents. It has a relatively high boiling point compared to straight-chain alkanes of similar molecular weight, reflecting the influence of branching on boiling point elevation. This compound is primarily used in research and as a reference standard in various analytical applications, including gas chromatography. Additionally, it is a component in the study of fuel properties and octane ratings, as branched alkanes generally exhibit higher octane numbers than their straight-chain counterparts. Safety precautions should be taken when handling this substance, as it may pose health risks if inhaled or ingested.
