Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of active pharmaceutical ingredients (APIs) due to its ability to form hydrogen bonds and participate in selective binding with biological targets. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing antitumor and anti-inflammatory agents. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
