A novel mannich base was synthesized from maleimide and morpholine. Its structural features have been established based on the data obtained from the FT-IR, UV-visible, Mass, and NMR spectra. The structural parameters such as the bond angle, and bond length were also been determined theoretically using the DFT calculations. The antioxidant property of the title compound was studied using DPPH free radical scavenging property. The antimicrobial activity is studied with the microorganisms such as Escherichia coli, Staphylococcus aureus, Aspergillus niger, and Candida albicans employing the agar-well diffusion method.
