    • note
    • At present, no direct assay is available to monitor the formation of oxazolone specifically and quantitatively accurate enough. The employed indirect fluorescence-labeling HPLC assay requires alkaline treatment not only for the release of guanidine from oxazolone but also for its condensation with NQS. This prevents a clear distinction to be made between free and released guanidine.
