Acetophenone

Acetophenone (CAS 98-86-2, EC 202-708-7, formula C8H8O) is an aromatic ketone commercially known under names including Hypnone and FEMA 2009. It carries no assigned E-code and is classified within the flavors and fragrances category for industrial and formulation use.

In UV-curable coatings and printing inks, acetophenone acts as a photoinitiator, absorbing UV radiation to generate reactive species that trigger polymer crosslinking. In food and fragrance formulations, it contributes sweet, floral top notes at controlled concentrations, and in polymer processing it functions as a heat stabilizer, interrupting oxidative degradation chains.

Acetophenone is supplied as a liquid and is available in food-grade quality meeting FCC specifications, with REACH compliance documentation standard for European supply. It falls under HS code 29143900. Procurement quantities typically range from drum to IBC, with documentation including SDS, CoA, and origin declarations on request.
