Phenylacetic acid (conjugate base phenylacetate), also known by various synonyms, is an organic compound containing a phenyl functional group and a carboxylic acid functional group. It is a white solid with a strong honey-like odor .
Sulfonation gives the "alpha" product naphthalene-1-sulfonic acid as the kinetic product but naphthalene-2-sulfonic acid as the thermodynamic product. The 1-isomer forms predominantly at 25 °C, and the 2-isomer at 160 °C. Sulfonation to give the 1- and 2-sulfonic acid occurs readily: H 2 SO 4 + C 10 H 8 → C 10 H 7 SO 3 H + H 2 O
Phenylacetic, 3-phenylpropanoic and 3-phenylpropenoic acids are found in propolis, mammalian exocrine secretions or plant fragrances. During a systematic study of the lipids from seeds of the plant Araceae, [1] the presence of 13-phenyltridecanoic acid as a major component (5-16% of total fatty acids)was discovered. Other similar compounds but ...
Phenylacetaldehyde is an organic compound used in the synthesis of fragrances and polymers. [1] Phenylacetaldehyde is an aldehyde that consists of acetaldehyde bearing a phenyl substituent; the parent member of the phenylacetaldehyde class of compounds.

Methyl phenylacetate is an organic compound that is the methyl ester of phenylacetic acid, with the structural formula C 6 H 5 CH 2 CO 2 CH 3. It is a colorless liquid that is only slightly soluble in water, but soluble in most organic solvents. Methyl phenylacetate has a strong odor similar to honey.
With a pK a of 12.34 [4] for its conjugate acid in aqueous solution, 1,8-bis(dimethylamino)naphthalene is one of the strongest organic bases. However, it only absorbs protons slowly—hence the trade name. The high basicity is attributed to the relief of strain upon protonation and/or the strong interaction between the nitrogen lone pairs.
