Chemical Structure
Description
Structurally, 2-(Allylthio)-4-(o-tolyloxy)benzo[4,5]thieno[3,2-d]pyrimidine (C20H16N2OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 364.48 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.
