Chemistry, Properties & Perfumer Guide
The Chemistry
This compound is a synthetic copper(II) complex of a modified phorbinepropionate ester, featuring an extended phytyl side chain. The porphyrin-like structure contains a central copper atom coordinated within the macrocyclic framework. Synthesis would require multi-step organic transformations including esterification and metal chelation. The complex molecular architecture suggests potential chirality at multiple centers, though specific optical properties are undocumented.
