Used as a key intermediate in the synthesis of fungicides, particularly in agricultural chemistry for controlling plant pathogens. The structure, featuring a pyridine ring and cyano group, supports binding to specific enzyme sites in fungi, disrupting their growth and exhibiting strong activity against a range of fungi. This makes it valuable in crop protection formulations. Commonly applied in the development of systemic fungicides that are effective when absorbed by plant tissues. Also utilized in research for designing new agrochemicals with improved efficacy and environmental safety.
