Description

6-Sulfonicotinic Acid is a versatile sulfonated derivative of nicotinic acid, serving as a key organic intermediate and building block in advanced chemical synthesis. Its value lies in its bifunctional structure, which incorporates both a carboxylic acid and a sulfonic acid group, enabling its use in the production of specialized fine chemicals and active pharmaceutical ingredients (APIs). This compound is particularly relevant for manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop new compounds or modify existing ones.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of novel drug candidates, particularly those requiring sulfonamide or sulfonic acid functionalities.
• Agrochemical Synthesis: Used in the manufacturing of advanced herbicides, pesticides, and plant growth regulators where the sulfonic acid group enhances solubility or biological activity.
• Dye and Pigment Production: Acts as an intermediate for creating water-soluble dyes and high-performance pigments, leveraging its ionic character.
• Ligand and Chelating Agent: Its structure makes it suitable for developing ligands used in catalysis or metal ion sequestration processes.
• Chemical Research & Development: Employed in academic and industrial R&D labs for exploring new organic reactions and synthesizing complex molecular architectures.
• Surface Active Agent Precursor: Can be used in the synthesis of specialty surfactants and detergents with unique properties.

Quality Control

Our 6-Sulfonicotinic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets exacting standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability, consistency, and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
