Description

Pyridine-3-sulfonic acid sodium salt offers a stable, water-soluble anionic platform for functionalization in synthetic and biochemical applications. The sulfonate group enhances solubility and provides a robust anchor for further derivatization, while the pyridine ring enables coordination or π-stacking interactions. This salt form ensures reliable handling and consistent performance under standard conditions.

Application

Pyridine-3-sulfonic acid sodium salt serves as a versatile, bench-stable sulfonating agent and synthetic intermediate. It facilitates electrophilic sulfonation reactions under mild conditions and functions as a polar, water-soluble scaffold in the construction of bioactive heterocycles. Its sodium counterion enhances solubility in aqueous and mixed solvent systems, enabling efficient purification and compatibility with standard reaction workflows.
