Acridone

Acridone (CAS 578-95-0, EC 209-434-7) is a nitrogen-containing polycyclic organic compound, also known commercially as CK 103, Acridon, and Acridanone, with the molecular formula C13H9NO. It carries no assigned E-code and is classified under HS code 29339900 within the broader pigments and colorants category.

In printing inks and coatings, acridone functions as an organic pigment and photoinitiator, absorbing UV radiation to trigger polymerization in energy-curable systems. In personal care formulations, it acts as a skin conditioner and antioxidant by scavenging free radicals and stabilizing oxidation-sensitive ingredients. Textile and leather applications exploit its colorant properties for substrate dyeing and surface modification.

Acridone is supplied as a crystalline powder and is subject to REACH registration requirements for EU market compliance. Buyers should confirm supplier documentation including Safety Data Sheets and certificates of analysis. Standard packaging formats vary by supplier; procurement teams should request batch-specific purity data and confirm grade suitability for their target application.
