Chemical Structure
Description
Structurally, (2-(9H-Carbazol-9-yl)ethyl)phosphonic acid (C14H14NO3P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphonate group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 275.24 g/mol, it falls into the medium-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.
