Application

  • Synthesis of pyrazolopyranopyrimidines: A study employed a Co-MOF@Ag(2)O nanocomposite as a nano-organic catalyst for the efficient one-pot synthesis of pyrazolopyranopyrimidines, highlighting its potential application in organic synthesis involving barbituric acid derivatives (Hootifard et al., 2023).
  • Optical and electrochemical characterization of organic dyes: Research on the optical, electrochemical, thermal, and theoretical properties of carbazole-derived organic dyes noted implications for the synthesis methods and applications of barbituric acid in dye chemistry, indicating advancements in material science (Naik et al., 2024).
