3-Amino-5-methylisoxazole Usage And Synthesis
Chemical Propertiesyellow crystalline powder, crystals and chunks
UsesSulfamethoxazole (SMX) (S699086) Impurity. A degradation product in water by a bioluminescence method during application of the electro-Fenton treatment.
Uses3-Amino-5-methylisoxazole was used in synthesis of:
  • naphtho[1,2-e][1,3]oxazines
  • series of 1-aryl-4-methyl-3,6-bis-(5-methylisoxazol-3-yl)-2-thioxo-2,3,6,10b-tetrahydro-1H-pyrimido[5,4-c]quinolin-5-ones, having potential mosquito larvicidal activity
  • hydroxylamines of sulfadiazine and sulfamethoxazole
General Description3-Amino-5-methylisoxazole is the major intermediate formed during sulfamethoxazole biodegradation by Pseudomonas psychrophila strain HA-4. It is the intermediate formed during the photocatalytic degradation of sulfamethoxazole (SMX).
