From Wikipedia, the free encyclopedia

1-Heptanol is an alcohol with a seven carbon chain and the structural formula of                          1-Heptanol
CH3 (CH 2 ) 6 OH. [1] It is a clear colorless liquid that is very slightly soluble in
water, but miscible with ether and ethanol.

Overview
There are three other isomers of heptanol that have a straight chain, 2-heptanol,
3-heptanol, and 4-heptanol, which differ by the location of the alcohol functional
group.                                                                                                    IUPAC name

Heptanol is commonly used in cardiac electrophysiology experiments to block gap                           Heptan-1-ol

junctions and increase axial resistance between myocytes. Increasing axial                                Other names
