Abstract: The tautomerism of hymexazol was confirmed by GC-MS and 1H NMR analysis. 1H NMR of hymexazol under different temperatures indicated that the isomerization of hymexazol was affected slightly by temperature changes. And the main isomer was enol which was about 98.2% at 20℃. The result also proved that GC analysis was reliable for the sample.

Key words: Hymerxazol, Tautomerism, 1H NMR
