Chemical Structure
Description
Structurally, 5309-35-3 N'-[(3-Bromophenyl)methylidene]-4-oxo-3,4,5,6,7,8-hexahydro[1]benzothieno[2,3-d]pyrimidine-2-carbohydrazide DTXSID60361326 (C20H30O4) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 334.45 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.
