Description
2-Ethylanthraquinone (CAS 84-51-5, EC 201-535-4, formula C16H12O2) is an anthraquinone derivative known under trade names including Kayacure 2-EAQ and identifiers such as NSC 7216 and β-Ethylanthraquinone. It carries no assigned E-code and is classified under HS code 29146990.
In UV-curable printing inks and coatings, 2-ethylanthraquinone functions as a Type II photoinitiator, absorbing UV radiation and generating reactive radicals through hydrogen abstraction to trigger polymer crosslinking. It is also employed in hydrogen peroxide production via the anthraquinone oxidation process, and as a soluble dye or colorant in textile and paper applications.
This material is supplied as a powder or crystalline solid and is subject to REACH registration requirements within the EU. Buyers should confirm supplier documentation including SDS and certificate of analysis. Standard packaging formats vary by supplier; bulk and drum quantities are typically available for industrial procurement.
