For characterizing keto acids, paper chromatography of their DNPHa is most widely used irrespective of the disadvantages (1)) some of which are as follows: According to the methods reported before 1962, the DNPH formed by the usual method were extracted from water solution with an organic solvent su

Thin-layer chromatography of keto acid 2,4-dinitrophenylhydrazones was carried out on plate coated with silica gel and sodium bicarbonate. A clear separation was obtained between most of the various keto acid hydrazones. The hydrazone was eluted from the plate with methanol containing 1% concentrate
