dibenzo[b,d]thiophene 5-oxide; CAS No.: 1013-23-6; dibenzo[b,d]thiophene 5-oxide. PROPERTIES: This sulfur oxide-substituted dibenzo thiophene features molecular formula C??H?O S with molecular weight 204.26 g/mol. It typically exists as a white crystalline powder. Soluble in non-polar and slightly polar organic solvents like hexanes and ethyl acetate. Melting point approximately 90-95 C. Exhibits IR absorption for S=O (~1100 cm??) and aromatic C-H stretches. Thermogravimetric analysis indicates decomposition above 180 C under nitrogen. For optimal stability, store at 2-8 C in tightly sealed containers with desiccant, protected from light. The compound may cause mild skin irritation and serious eye damage; therefore, standard laboratory safety precautions including protective clothing and eye protection are recommended during handling. APPLICATIONS: As a sulfur oxide-substituted dibenzo thiophene, dibenzo[b,d]thiophene 5-oxide is predominantly utilized in the synthesis of liquid crystal materials. It serves as a key intermediate in constructing mesogenic units for liquid crystal displays, where the sulfur oxide group provides valuable polarity for alignment and response properties as demonstrated in materials science research (Liquid Crystals). Additionally, the compound participates in the development of fluorescent probes for bioimaging applications, where its thiophene framework enables conjugation to fluorophores with enhanced photostability (Bioconjugate Chemistry). In environmental chemistry, it functions as a model compound for studying dibenzo thiophene oxidation processes in petroleum refining, where the sulfur oxide group provides insights into desulfurization mechanisms (Energy & Fuels).
