Description

4-(4-Methylphenyl)-1-Butene is a specialized organic intermediate featuring a phenyl ring substituted with a methyl group and a terminal butene chain. This unique structure makes it a valuable building block for synthesizing more complex molecules in fine chemical and pharmaceutical research. It is primarily sought after by R&D chemists and process development scientists working in advanced material science and active pharmaceutical ingredient (API) development.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel therapeutic compounds and active pharmaceutical ingredients (APIs).
• Liquid Crystal & OLED Material Research: Used in the development of advanced organic electronic materials due to its aromatic and alkenyl functionality.
• Agrochemical Synthesis: Acts as a building block for creating new generation pesticides and herbicides.
• Polymer & Resin Modification: Employed to introduce specific aromatic side-chains into polymers, altering their physical and chemical properties.
• Organic Synthesis & Catalysis Research: Utilized in cross-coupling reactions and as a model substrate in methodological development for creating carbon-carbon bonds.
• Fragrance & Flavor Chemistry: Investigated for the synthesis of aromatic compounds used in specialty fragrance applications.
