Anwendung

3-Hydroxy-5-methylisoxazole can be used as a reactant to synthesize:
  • 3-Oxoisoxazole-2(3H)-carboxamides by reacting with dimethyl-carbamoyl chloride in the presence of potassium t-butoxide.
  • Hydroxymethyl-2-propen-1-yl-5-methyl-3(2H)-isoxazolone via ring-opening reaction with vinyl oxirane.

Hymexazol is an efficacious and widely used fungicide. However, its environmental toxicological assessment has not been well documented. It had no report of its toxicity to fish embryo. Fish embryo acute toxicity tests are highly predictive of aquatic embryotoxicity outcome.
