This paper describes the use of the mass spectrometry (MS), thermal analyses (TA) and other physico-chemical methods to investigate
the structure of two newly synthesized phenolic-iodine derivative polymeric products. These two products are formed as a result
of redox-interaction of adrenaline hydrogen tartrate (AHT, I) with iodate (IO-3) and periodate (IO-4). The characterization of the two products were achieved satisfactorily by using the above tools and their proposed general
formulae, were found to be C52H67O36N4I (AHT- IO-3, II) and C26H34O18N2I2(AHT- IO-4, III). The fragmentation behavior of the main compound (AHT) in MS and TA (TG and DTA) techniques was investigated and compared.
The results obtained were used to explain the fragmentation of the products AHT- IO-3and AHT- IO-4in mass spectrometry and thermal analyses techniques. The stabilities of different fragments were discussed. The results indicate
that the two techniques are supporting each other in which the mass spectrometry provides the structural information in gas
phase while the thermal analyses provides the quantitative fragmentation in the solid-state.
