Common Name | N-Heptane |
---|
Description | N-Heptane, also known as heptan or CH3-[CH2]5-CH3, belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2 , and therefore consisting entirely of hydrogen atoms and saturated carbon atoms. Thus, N-heptane is considered to be a hydrocarbon lipid molecule. N-Heptane is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. N-Heptane is a sweet, alkane, and ethereal tasting compound. N-heptane has been detected, but not quantified, in cardamoms and gingers. This could make N-heptane a potential biomarker for the consumption of these foods. This is done by shaking the stained paper in a heptane solution for about half a minute. N-Heptane is a potentially toxic compound. It was originally chosen as the zero point of the scale because of the availability of very high purity n-heptane, unmixed with other isomers of heptane or other alkanes, distilled from the resin of Jeffrey pine and from the fruit of Pittosporum resiniferum. As a liquid, it is ideal for transport and storage. The 2,2-dimethylpentane isomer can be prepared by reacting tert-butyl chloride with n-propyl magnesium bromide. The linear n-heptane can be obtained from Jeffrey pine oil. In water, both bromine and iodine appear brown. n-Heptane is the straight-chain alkane with the chemical formula H3C(CH2)5CH3 or C7H16. |
