4-hydroxy acetophenone

4-Hydroxyacetophenone (CAS 99-93-4), also known commercially as piceol, is a phenolic ketone used across food, cosmetic, and industrial manufacturing. It functions as a photoinitiator, antioxidant, and flavoring agent depending on the application sector. In UV-curable systems for printing inks and packaging coatings, it acts as a photoinitiator to trigger polymerization under UV exposure. Cosmetic formulators incorporate it as an antioxidant and skin-brightening active in serums and creams.

In food and beverage, it is approved under FEMA 4330 as a flavoring ingredient, contributing subtle phenolic and sweet notes to finished products. It is also used as an intermediate in the synthesis of active pharmaceutical ingredients. Pharmaceutical manufacturers source it particularly where a para-substituted acetophenone scaffold is required. The material is supplied as a white to off-white crystalline powder available in various technical and high-purity grades.
