Structurally, Caspofungin Impurity 47(5-((3R)-3-Hydroxy-L-Ornithine)-Pneumocandin B0) Acetate (C50H82N8O16C2H4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, 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 1111.30 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a process- or degradation-related impurity, Caspofungin Impurity 47(5-((3R)-3-Hydroxy-L-Ornithine)-Pneumocandin B0) Acetate (CAS 150283-04-8 (free base), C50H82N8O16C2H4O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
