This product is white powdery solid, mp134～135℃, insoluble in water, soluble in methanol, ethanol and other organic solvents.

Pyrazole-1,3-dimethyl-5-phenoxy-4-carboxaldehyde oxime is an intermediate for the synthesis of the acaricide fenpyroximate.

1,3-Dimethyl-5-phenoxy-4-formylpyrazole was dissolved in methanol, and hydroxylamine hydrochloride was added, and pyrazole-1,3-dimethyl-5-phenoxy-4-carboxaldehyde oxime was finally obtained by the reaction.
