S2phenylpropanoic

S2phenylpropanoic acid, also known as 2-phenylpropanoic acid or hydratropic acid, is an organic compound with the chemical formula C9H10O2. It is a carboxylic acid and a derivative of propanoic acid where a phenyl group is substituted at the second carbon atom. This compound is a chiral molecule, meaning it exists as two stereoisomers, (R)-2-phenylpropanoic acid and (S)-2-phenylpropanoic acid, as well as a racemic mixture.

S2phenylpropanoic acid is a colorless liquid or solid at room temperature, depending on its purity and specific form. It is sparingly soluble in water but readily dissolves in common organic solvents such as ethanol and ether. Its synthesis can be achieved through various chemical routes, often involving reactions of phenylacetic acid derivatives or styrene.

This compound and its derivatives have found applications in organic synthesis. It can serve as a building block for the preparation of more complex molecules. The chiral nature of S2phenylpropanoic acid is significant, as its enantiomers can exhibit different biological activities or reactivities in asymmetric synthesis. While not as widely known as some other carboxylic acids, S2phenylpropanoic acid is a useful intermediate in specialized chemical processes.
