Application

  • N-sulfonic acid pyridinium-4-carboxylic acid chloride as a catalyst: This study describes the use of this compound as a catalyst for the condensation reaction of aldehyde with thiobarbituric acid. The catalytic performance is characterized in the context of improving reaction efficiency (Moosavi-Zare, Afshar-Hezarkhani, 2020).
  • Synthesis of Anti-inflammatory Substances: Focused on the synthesis of potential anti-inflammatory substances among triazole thioacetamides derived from 4-pyridinecarboxylic acid, this study expands on the pharmacological potentials of pyridine derivatives (Syrovaya, Chalenko, Demchenko, 2016).
