phenolacetone

Phenolacetone is not a widely used or standard chemical name in major reference databases. In published sources it can appear as a mistaken or informal term, and its precise meaning is unclear without context. When encountered, it may be a misspelling or shorthand for one of two distinct classes of compounds: phenylacetone (P2P) or certain hydroxy-substituted acetophenones. Because of this ambiguity, a precise definition should be confirmed from the source.

Phenylacetone, also known as 1-phenyl-2-propanone or P2P, is a ketone with a phenyl group attached to a propanone backbone (Ph-CH2-CO-CH3). It is a precursor in various industrial syntheses and has historically been associated with illicit drug manufacture in some jurisdictions. As a chemical, it is typically handled as a colorless liquid or low-boiling liquid under normal conditions, and it is subject to regulatory controls in many countries. Hazards include irritation to the skin, eyes, and respiratory tract; it is also flammable and should be stored away from heat and oxidizers with appropriate ventilation and protective equipment. Regulatory status varies by country, with some jurisdictions restricting its sale, transfer, and distribution as a controlled precursor.

A second possible interpretation of the term—though not standard—would be a hydroxy-substituted acetophenone, such as 4-hydroxyacetophenone. These compounds are used as fragrance ingredients and as intermediates in organic synthesis, and they are chemically distinct from phenylacetone.

In summary, phenolacetone is not a defined chemical in common references; when encountered, it should be clarified whether the intended compound is phenylacetone (P2P) or a hydroxy-substituted acetophenone to avoid confusion.
