6,11-dihydrodibenzo[b,e]thiepin-11-one; CAS No.: 1531-77-7; 6,11-dihydrodibenzo[b,e]thiepin-11-one. PROPERTIES: 6,11-dihydrodibenzo[b,e]thiepin-11-one appears as a white to off-white crystalline powder with a slight sulfur odor. Its molecular formula is C17H13NO2S, corresponding to a molecular weight of approximately 383.37 g/mol. The compound exhibits a melting point in the range of 190-193 C and demonstrates moderate solubility in common organic solvents such as methanol, ethyl acetate, and dichloromethane 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: 6,11-dihydrodibenzo[b,e]thiepin-11-one serves as a valuable intermediate in the synthesis of pharmaceuticals, particularly in the preparation of certain antipsychotic and antidepressant agents where its thiepinone structure provides opportunities for receptor binding and bioactivity (Journal of Medicinal Chemistry). In materials science, 6,11-dihydrodibenzo[b,e]thiepin-11-one functions as a building block for creating organic semiconductors and field-effect transistors, leveraging its electron-rich sulfur-containing aromatic system to facilitate charge transport properties (Advanced Materials). Additionally, it finds application in the development of fluorescent probes and sensors, where its molecular structure allows for selective labeling and detection of biological targets (Analytical Chemistry). The compound is also employed in the synthesis of certain agrochemicals, though specific applications in this area are limited to non-agricultural research settings (Pest Management Science).
