Eleven new ortho-(meta- and para-)bromobenzylS-mono and S-N-1-disubstituted derivatives of 5-morpholinomethyl-2-thiouracil (MMTU) and 5-piperidinomethyl-2-thiouracil (PMTU) have been prepared and their EI induced mass spectral fragmentation has been investigated. It has been shown that the data derived from EIMS spectra can be used to differentiate the isomers
