Used as an intermediate in the synthesis of sulfa drugs, particularly in the production of sulfonamide-based antibiotics. It plays a role in modifying the pharmacokinetic properties of active pharmaceutical ingredients by enhancing solubility and bioavailability. Also utilized in the development of diuretic agents and other therapeutic compounds where sulfonamide functionality is required. Its hydroxypropyl group allows for further chemical modifications, making it valuable in medicinal chemistry for creating derivatives with improved metabolic stability.
