Although it is a completely different ester, propyl hexanoate shares the same chemical formula with methyl octanoate, ethyl heptanoate, butyl pentanoate, etc.

[1] Due to the length of the carbon chain in this molecule, there are only minor van der Waals forces acting upon it, which is why propyl hexanoate appears as a liquid and not a solid.

The hydroxyl group from the propanol reacts with the hydroxyl group from the hexanoic acid to produce water and leave an oxygen that the parent acid and alcohol chains bond to, creating the ester.

This reaction occurs between the ester and water in the presence of a dilute acid catalyst and heat.

[3] Propyl hexanoate, being an ester, is generally used for replicating the scents or flavors of fruit such as blackberry and pineapple, then is added to things such as food or perfume.
