Synthesis, Characterization and Antioxidant Activity of 2-Halobenzoyl Thiourea bearing α- and β-Alanine
Six new 2-halobenzoylthiourea compounds bearing α- and β-alanine have been successfully synthesized and characterized using CHNS microelemental analysis and spectroscopic methods including FTIR, UV-Vis and NMR. Microelemental analysis data of the compounds were in agreement with the theoretical valu...
