but2ene14diol

But-2-ene-1,4-diol is an organic compound with the chemical formula C4H8O2. It is a diol, meaning it contains two hydroxyl (-OH) functional groups. The "but-2-ene" part of the name indicates a four-carbon chain with a double bond located between the second and third carbon atoms. The "1,4-diol" specifies that the hydroxyl groups are attached to the first and fourth carbon atoms of this chain.

This compound can exist as geometric isomers due to the double bond. These are cis-but-2-ene-1,4-diol and trans-but-2-ene-1,4-diol. The cis isomer has both hydroxyl groups on the same side of the double bond, while the trans isomer has them on opposite sides. These isomers can exhibit different physical and chemical properties.

But-2-ene-1,4-diol is typically a colorless liquid or solid, depending on the isomer and purity. It is soluble in water and polar organic solvents due to the presence of the hydroxyl groups, which can form hydrogen bonds.

Industrially, but-2-ene-1,4-diol can be synthesized through various chemical processes. One common method involves the reduction of maleic anhydride or its derivatives. It serves as a valuable intermediate in the synthesis of other organic compounds, including polymers, pharmaceuticals, and fragrances. Its unsaturated nature and the presence of two hydroxyl groups make it a versatile building block in organic chemistry.
