Impurity Analysis of Tamoxifen and Toremifene Samples Obtained by McMurry Reaction Elisabetta Brennaa, Giovanni Fronzaa, Claudio Fugantia, Grato Angelo Magnoneb, and Cesare Pellegattab Dipartimento di Chimica, Materiali ed Ingegneria Chimica del Politecnico, Istituto CNR per la Chimica del Riconoscimento Molecolarea, and Laboratori Magb, Milano (Italy) The structure of two impurities of commercial samples of tamoxifen (CAS 10540-29-1) and toremifene (CAS 89778-26-7), prepared by McMurry procedure, were characterised by spectroscopic methods. The two impurities were found to be strictly connected with the synthesis procedure. Their detection can be useful to trace back the synthesis route of a sample. Key words CAS 10540-29-1 • CAS 89778-26-7 • McMurry reaction • Tamoxifen, impurities • Toremifene, impurities |
