Notes:
The mass spectral fragmentation of hydroxyhydantoins was studied by a combination of high-resolution, linked-scan and collisionally activated decomposition (CAD) experiments. This endeavor resulted in the structural assignment of four pairs of synthetic hydroxyhydantoin isomers. A key feature in differentiating l-methyl-3- aryl-5-hydroxy-2,4-imidazolidinediones from 1-aryl-3-methyl-5-hydroxy-2,4-imidazolidinediones is that under electron ionizarion (EI) conditions only the 1-methyl-3-aryl-5-hydroxy-2,4-imidazolidinediones yield the [MeNHCHO]+· ion. The analogous [ArNHCHO]+· ion (where Ar is the aryl group) was present in the EI spectra of both isomers and its origins are explained by the linked-scan and CAD experiments performed.
