Application
Fenethanil, also known as fenbuconazole (CAS 114369-43-6), is a systemic triazole fungicide used to control a wide range of fungal diseases in agriculture and horticulture. As a sterol biosynthesis inhibitor (SBI), it specifically targets the cytochrome P450-dependent enzyme lanosterol 14α‑demethylase (CYP51), disrupting ergosterol synthesis and compromising fungal cell membrane integrity. This triazole compound exhibits both protectant and curative activities, effectively controlling leaf spot, yellow and brown rust, powdery mildew, net blotch on wheat and barley, as well as apple scab, pear scab, and powdery mildew on pome fruits. With broad‑spectrum efficacy and systemic uptake, fenbuconazole is applied as a foliar spray in cereals, fruits, vegetables, and citrus crops, contributing to improved grain quality and yield. Beyond crop protection, the compound is routinely used as an analytical reference standard for pesticide residue analysis in soil, water, and food matrices, supporting regulatory compliance, method development, impurity profiling, quality control, and ANDA filings. Xinchem offers custom synthesis, custom chemical synthesis, and contract manufacturing of high‑purity fenbuconazole with reliable global supply and comprehensive regulatory documentation, scaled flexibly from R&D to commercial tons.
