Description

3-(4-Cyanophenyl)-1-Propene is a versatile aromatic nitrile derivative featuring a reactive terminal alkene group. This unique bifunctional structure makes it a valuable high-purity chemical intermediate for advanced synthesis in pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds containing styryl or cinnamyl motifs attached to an aromatic nitrile.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides where the cyano and alkene functionalities contribute to biological activity.
• Liquid Crystal & OLED Materials: Serves as a precursor for advanced electronic materials, where its rigid, conjugated structure is beneficial for charge transport properties.
• Polymer & Resin Modifier: The alkene group allows for copolymerization or grafting onto polymer backbones to introduce polar cyano groups, modifying material properties.
• Organic Synthesis Reagent: Employed in Heck reactions, hydrocyanations, and other cross-coupling or functional group transformation protocols in fine chemical production.

Quality Control

Every batch of 3-(4-Cyanophenyl)-1-Propene is produced and tested under a strict quality management system. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles to ensure it meets the exacting standards for research and scale-up. Our quality commitment supports compliance with REACH and other global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
