Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfonamide-based drugs with antimicrobial and anti-inflammatory properties. It serves as a building block in medicinal chemistry due to its ability to enhance binding selectivity and metabolic stability in drug candidates. Also employed in agrochemical research for designing herbicides and plant growth regulators. Its pyridine ring structure facilitates coordination in catalytic systems, making it useful in certain industrial catalyst formulations.
