Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive and anti-inflammatory drugs. It serves as a building block in the development of kinase inhibitors and other biologically active compounds due to its ability to form hydrogen bonds and participate in aromatic interactions. Also applied in agrochemical synthesis for creating herbicides and pesticides with improved selectivity. Its structural features, including the amino, hydroxy, and chloro substituents on the pyridine ring, make it valuable in medicinal chemistry for optimizing drug potency and metabolic stability.
