Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with anti-inflammatory and analgesic properties. It serves as a building block in heterocyclic chemistry, enabling the construction of complex pyrazole derivatives that exhibit biological activity. Its ester functionality allows for easy modification, making it valuable in medicinal chemistry for structure-activity relationship (SAR) studies. Also employed in agrochemical research for designing new pesticides and herbicides due to the pyrazole core’s favorable interaction with biological targets.
