Octamethylporphyrin was readily obtained from ethyl 3,4,5-trimethylpyrrole-2-carboxylate. Steric control can be overridden by apparent electronic effect is demonstrated by the even bulkier pyrrole derivative, ethyl 3,4,5-trimethylpyrrole-2-carboxylate. The reaction with diazonium salts of theEthyl 3,4,5-trimethylpyrrole-2-carboxylatehas been examined in detail by chromatographic and spectroscopic methods. In the presence of a strong mineral acid, Ethyl 3,4,5-trimethylpyrrole-2-carboxylate reacts with p-nitrobenzenediazonium ions to give a red, chemically labile, azo dye.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
