Aligned with advancements in synthetic chemistry, this work presents the synthesis and characterization of meglumine sulfate using FT-IR and CHNS analysis. Subsequently, the potential of the synthesized catalyst is explored in the preparation of a class of nitrogen-containing heterocyclic compounds (indenoindolones), which possess significant medicinal and biological properties. The study also reports the optimization of reaction conditions to enable the efficient synthesis and characterization of a broad spectrum of these compounds. Notably, the utilization of meglumine sulfate offers several advantages, including exceptional yields, cost-effectiveness, rapid reaction times, and facile product purification
