Abstract
Electron ionization mass spectra of 1,2-dihydro-2-[2-(1',3'-benzothiazo-lyl )]-3H-indazol-3-one (2a) and 1,2-dihydro-2(3',4'-dimethylphenyl)-6,7-dimeth oxy-3H-indazol-3-one (2b) and their related compounds (1a-b) are described with the help of LREIMS. The molecular formulae are further confirmed by hi gh resolution peak matching of molecular ion peaks exhibited by EIMS.
