3,3'-diaminobenzophenone; CAS No.: 611-79-0; 3,3'-diaminobenzophenone. PROPERTIES: 3,3'-diaminobenzophenone appears as a white to off-white crystalline powder with a slight amine odor. Its molecular formula is C13H12N2O, corresponding to a molecular weight of approximately 212.25 g/mol. The compound exhibits a melting point in the range of 180-183 C and demonstrates moderate solubility in common organic solvents such as methanol, ethyl acetate, and dimethylformamide while being sparingly soluble in water. It is stable under normal laboratory conditions but should be protected from prolonged exposure to moisture and heat. Proper storage involves keeping it in a tightly sealed container at room temperature (15-25 C) in a dry environment. Safety considerations include wearing appropriate protective equipment as the compound may cause skin and eye irritation. Inhalation of dust should be avoided, and in case of accidental exposure, thorough washing with water and medical consultation is advised. APPLICATIONS: 3,3'-diaminobenzophenone functions as a versatile intermediate in the synthesis of pharmaceuticals, particularly in the preparation of certain anticancer agents and anti-inflammatory drugs where its diamino and benzophenone groups provide opportunities for further functionalization and bioactive molecule design (Journal of Medicinal Chemistry). In materials science, 3,3'-diaminobenzophenone serves as a building block for creating polyurethanes and epoxy resins with enhanced thermal and mechanical properties, leveraging its ability to form cross-linked networks through its amine and ketone functionalities (Polymer Chemistry). Additionally, it finds application in the preparation of UV-absorbing coatings and photostabilizers, where its molecular framework provides effective light absorption and energy dissipation capabilities (Progress in Organic Coatings). The compound is also employed in organic synthesis as a starting material for the preparation of chiral building blocks through asymmetric transformations, enabling the synthesis of complex molecules with high stereochemical control (Tetrahedron Letters).
