The industrial production of oxpoconazole fumarate begins with the construction of a 1,2,4-triazole core, which is then alkylated with a 4-chlorophenylpropyl group to enhance antifungal activity. A hydroxylated side chain is introduced to improve systemic absorption, and the final compound is reacted with fumaric acid to form a stable salt, improving solubility and formulation compatibility. The resulting crude product is purified and formulated for agricultural use.
