Useful:

• Chemical Classes: Solvents -> Aliphatics, Saturated (
• Canonical SMILES: CCCCCCC
• Inhalation Risk: A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20 °C.
• Effects of Short Term Exposure: The substance is irritating to the skin. The vapour is irritating to the respiratory tract. If swallowed the substance easily enters the airways and could result in aspiration pneumonitis. The substance may cause effects on the central nervous system.
• Effects of Long Term Exposure: The substance defats the skin, which may cause dryness or cracking.

Technology Process of Heptane

There total 337 articles about Heptane which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology.
