✦ Synopsis

A sunple method for the detemunatlon of 2-thlohydantoms based on the mductlon of the lodme-azlde reactlon was developed The consumption of lodme IS proportional to the amount of the Inductor The mducmg properties of different compounds (S2-) were estunated from the mductlon coefficient <rI]/[Sj) which mdlcates how many tunes the consumption of Iodine m the Induced reachon is higher than that III the lodunetrlc reaction Under analytlcally optunum condltlons the mductlon coefficients were m the range 270-307 for SIX 2-thlohydantoms and 138-192 for four 3-phenyl-2-thlohydantoms The apphcabihty of the mdme-azide reaction for the determmatlon of microgram amounts of 2-thlohydantoms after theu separation by thm-layer chromatography 1s demonstrated The lodme-azide method IS sensttlve, selective, accurate, cheap and rapld Keywords Thin-layer chromatography, Iodine-azlde reaction, Thlohydantoms,
