Synthesis and characterization of a methacrylate monomer with a thiohydantoin structure
The purpose of the current study was to synthesize a methacrylate monomer with a thiohydantoin structure. In a flask, (2-thiohydantoin-4-yl) propionic acid, 10-hyroxydecyl methacrylate, 4-dimethylaminopyridine, and tetrahydrofuran (THF) were placed in a nitrogen atmosphere.

A FLUORIMETRIC ASSAY FOR MINUTE AMOUNTS OF SOME THIOHYDANTOINS
Abstract A fluorimetric assay sensitive to μg. quantities of certain thiohydantoins has been devised using dichloroquinone chloroimide as a fluorescence reagent. The nature of the buffer used is critical. Satisfactory results have been obtained for recoveries from urine, spinal fluid and plasma.
