Chemical Structure
Description
Structurally, 2,5-Dihydro-3,6-dithieno[3,2-b]thien-2-ylpyrrolo[3,4-c]pyrrole-1,4-dione (C18H8N2O2S4) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 412.53 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
