Sulfazan derivatives are a modern type of organic chemistry compounds, which is considered a recent innovation by Professor. Dr. Nagham Aljamali, who set the conditions for its preparation and properties and studied its stability and color fastness, also we investigated these compounds in the previous research via spectral techniques and we improved their structures, but here in this research, the work on studying its effectiveness and efficiency against breast tumors was completed, and we took two types of cells, one of them healthy and the other infected, for the purpose of comparing the efficiency of both derivatives (Invented Sulfazan and Formazan).
