Description

Sodium 3-(5-Mercapto-1-Tetrazolyl)Benzene Sulfonate is a specialized organic salt that serves as a critical intermediate and functional additive in advanced chemical synthesis. This compound matters for its unique combination of a sulfonate group for solubility and a reactive mercaptotetrazole moiety, enabling its use in high-performance applications where precise chemical functionality is required. Industries such as pharmaceutical manufacturing, photographic chemistry, and specialty polymer production need this chemical for developing sensitive materials and active pharmaceutical ingredients (APIs). Its specific structure makes it valuable for research and development in creating new compounds with tailored properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a tetrazole or thiol functional group for biological activity.
• Photographic Chemistry: Acts as an antifoggant or stabilizer in silver halide photographic emulsions and materials.
• Polymer & Resin Modification: Serves as a functional monomer or cross-linking agent to introduce ionic or reactive sites into specialty polymers and coatings.
• Corrosion Inhibitor Formulation: Utilized in advanced cooling water systems or metal treatment fluids where specific chelating and protective properties are beneficial.
• Analytical Reagent: Employed in research laboratories as a reagent for complexometric titrations or as a standard in chromatographic analysis.
• Electroplating Additive: Functions as a brightener or leveling agent in electroplating baths for specific metal deposition processes.

Quality Control

Our Sodium 3-(5-Mercapto-1-Tetrazolyl)Benzene Sulfonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for industrial and research applications. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory compliance needs.

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 sealed under dry conditions to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
