Usage

Pentenynol functional group

The molecule contains a pentenynol functional group, which consists of a five-carbon chain with a triple bond and a hydroxyl group.

Cyclohexenyl group

The molecule also includes a cyclohexenyl group, which is a six-carbon ring with a double bond.

3-Methyl substituent

A methyl group (CH3) is attached to the cyclohexenyl group at the 3-position, which adds complexity to the molecule.

2,6,6-Trimethyl substituents

Three methyl groups (CH3) are attached to the cyclohexenyl group at the 2and 6-positions, which further adds complexity to the molecule.

(1E)designation

The molecule has a cis configuration at the double bond, which means that the two substituents on the double bond are on the same side of the molecule.

Applications in organic chemistry

The compound may be used in the synthesis of pharmaceuticals or other complex organic molecules.
