Exploring quinolinone–chalcones: Synthesis, antioxidant potential and industrial applications in biofuels

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 1765-1783, November/December 2025.
Abstract Biofuels undergo oxidative degradation, which reduces their storage stability and efficiency, hindering their large‐scale adoption and integration into the global energy matrix. To address this issue, we synthesized and characterized four novel quinolinone–chalcone derivatives (substituted with Br, Cl, OCH3 and OCH2CH3) as potential ...
