1-Phenylpentadecan-1-one, with the CAS number 4669-04-9, is an organic compound characterized by its long hydrocarbon chain and a ketone functional group. It features a phenyl group attached to a pentadecanone structure, which consists of a 15-carbon straight-chain alkane with a carbonyl group (C=O) at the first position. This compound is typically a colorless to pale yellow liquid or solid, depending on the temperature and purity. It is relatively hydrophobic due to its long carbon chain, making it soluble in organic solvents but insoluble in water. The presence of the phenyl group contributes to its aromatic properties, which can influence its reactivity and interactions with other substances. 1-Phenylpentadecan-1-one may be used in various applications, including as a fragrance component, in organic synthesis, or as a potential intermediate in the production of other chemical compounds. Its physical and chemical properties, such as boiling point, melting point, and reactivity, can vary based on the specific conditions and purity of the sample.

Pentadecanophenone

Pentadecanophenone is a reactive organic solvent that is colorless, nonflammable and odorless. It is used as a microcapsule coating for portability. Pentadecanophenone can be reversibly polymerized to form polypentadecanophenones through the use of sodium salts or phenyl groups. This compound has been shown to have deuterium isotope effects in organic solvents. Pentadecanophenone has also been shown to be thermochromic, meaning it changes color when heated. Reactions with anthracene yields discoloring products that are not reversible on cooling.
