Myclobutanil is a triazole antifungal agent known for its ability to inhibit ergosterol biosynthesis, a component of fungal cell membranes. This broad-spectrum systemic fungicide acts as a potent inhibitor, making it effective in preventing fungal attacks on plants. It is particularly efficient against powdery mildew in vegetables and cereals. Not only does Myclobutanil serve as a fungicide, but it has also been found to induce cytochrome P450 enzymes. In addition to its agricultural uses, Myclobutanil has been identified as a contaminant in concentrated Cannabis extracts from the California medical Cannabis market. As such, it has become a subject of research and forensic applications. Chemically, Myclobutanil is a light yellow solid and belongs to the triazole class of compounds. Its structure consists of 2-(4-chlorophenyl)-2-(1H-1,2,4-triazol-1-ylmethyl)hexanenitrile—a nitrile with a hexanenitrile backbone substituted at the 2-position by p-chlorophenyl and (1,2,4-triazol-1-yl)methyl groups.
