Abstract: The present invention describes a method of purifying a pesticide that includes: a) melting a pesticide, wherein the pesticide includes at least on e active ingredient and at least one impurity capable of inhibiting crystallization; b) coating the pesticide on a substrate to form a pesticide particle; c) substantially reducing the amount of crys-tallization inhibitin g impurity by an azeotropic method; and d) crystallizing the pesticide. In another embodiment, the present invention includes a method of purifying a pesti-cide as described above, such that the pesticide has a melting point o f not more than about 90~C. Also included in the invention is the product produced by the above proc-ess for the pesticide, methyl N-(2-{[1-(4- chlorophenyl)-1H-pyrazol-3-yl]oxymethyl} phenyl)N-methoxy carbamate.
