trans-β-Nitrostyrene(CAT: R022496) is an electrophilic alkene featuring a nitro group conjugated to a styrene backbone in the trans configuration. This compound is a valuable synthetic intermediate in organic chemistry, commonly used in Michael additions, Henry reactions, and cycloaddition processes. Its electron-deficient double bond makes it highly reactive toward nucleophiles, enabling the formation of various nitrogen- and carbon-containing heterocycles. trans-β-Nitrostyrene is frequently employed in the synthesis of amines, amino acids, and biologically active molecules, including pharmaceutical precursors. Its defined geometry and strong electron-withdrawing nitro functionality offer excellent reactivity and selectivity in asymmetric and stepwise synthetic applications.
