4phenylbutanoic

4-Phenylbutanoic acid is an organic compound with the chemical formula C10H12O2. It is a carboxylic acid that features a phenyl group attached to the terminal carbon of a four-carbon chain. The molecule can be described as a butyric acid derivative where one of the terminal methyl hydrogens has been replaced by a phenyl group. It is also known by the synonym 3-phenylbutyric acid in older nomenclature, though the IUPAC name 4-phenylbutanoic acid is preferred.

In terms of its physical properties, 4-phenylbutanoic acid is typically a white crystalline solid at room temperature. Its solubility characteristics are influenced by both the polar carboxylic acid group and the nonpolar phenyl ring, meaning it exhibits some solubility in water and is more soluble in organic solvents.

The synthesis of 4-phenylbutanoic acid can be achieved through various organic chemistry routes, often involving reactions that build the carbon skeleton or introduce the phenyl group. Its chemical reactivity is characteristic of carboxylic acids, undergoing esterification, amide formation, and reduction. While not a widely produced commodity chemical, it may find applications as a building block or intermediate in the synthesis of more complex organic molecules within research and development settings, particularly in areas related to pharmaceuticals or specialty chemicals. Its specific biological or industrial significance is not widely documented.
