3-Phenylacrylic acid(CAS: 9045-22-1)

3-Phenylacrylic acid (CAS: 9045-22-1) is a crystalline solid with a molecular weight of approximately 142.17 g/mol. It is slightly soluble in water but soluble in most organic solvents. Chemically, it is relatively stable but can react with strong bases to form salts. It has a pKa of about 2.9, indicating acidic behavior.

3-Phenylacrylic acid is typically synthesized via the Wittig reaction, where phenyl methyl ketone reacts with phosphorus ylide. Another method involves the condensation of benzaldehyde with acrylic acid, followed by hydrolysis. This process yields a pure product with high selectivity and good yield under appropriate conditions.

3-Phenylacrylic acid (CAS: 9045-22-1) is used in various industries, including pharmaceuticals for the synthesis of certain drugs, in polymer production for modifying properties, in the development of sensors for chemical detection, and in semiconductors for specific applications. Its versatility makes it a valuable intermediate in organic synthesis.

When handling 3-Phenylacrylic acid (CAS: 9045-22-1), it is essential to wear appropriate personal protective equipment (PPE), including gloves and eye protection. It should be stored in a sealed container and away from strong bases. In case of spillage, use a fume hood for safety. Refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
