1) Starting with 2, 4- and 2, 5-dichlorobenzoic acid, through chloroxanthone, 2- and 3-monochloroxanthydrol were prepared and their properties as the estimation reagent for amides (amides, sulfonamides, urethan, substituted barbituric acid) were compared with xanthydrol.
2) It was thereby found that these compounds did not react with amides as easily as xanthydrol but were more stable and it was possible to use them as a supplement for the qualitative reagent for the foregoing amides. The melting point of the condensation products was examined.
