Description

4-(4-Ethoxyphenyl)-1-Butene is a specialized organic intermediate featuring an ethoxy-substituted phenyl ring attached to a terminal alkene chain. This unique structure makes it a valuable building block for synthesizing more complex molecules in fine chemical and pharmaceutical research. It is particularly sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for constructing novel compounds.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs) and novel drug candidates, particularly those requiring a phenethylamine or styrene derivative framework.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and plant growth regulators, leveraging its aromatic and alkene functionality.
• Liquid Crystal & OLED Material Research: Serves as a starting material for creating advanced organic electronic materials and liquid crystal compounds due to its rigid aromatic core and modifiable alkene group.
• Fine Chemical Building Block: Employed in organic synthesis for cross-coupling reactions (e.g., Heck reaction) and as a scaffold for creating specialty chemicals, flavors, and fragrances.
• Polymer & Resin Modifier: Can be incorporated as a monomer or co-monomer to introduce specific aromatic properties into polymers or to act as a cross-linking agent.
