Description

Trisodium Nitrilotrimethanesulphinate CAS NO 23714-12-7 is the trisodium salt of nitrilotrimethanesulfinic acid, a versatile and highly effective reducing agent and chelating compound. Its primary commercial value lies in its ability to act as a powerful oxygen scavenger and stabilizer, protecting sensitive formulations from oxidative degradation. This makes it a critical material for manufacturers in the pharmaceutical, photographic, textile, and water treatment industries who require reliable protection for their products and processes.

Application

• Pharmaceutical Synthesis & Stabilization: Used as an antioxidant and reducing agent in active pharmaceutical ingredient (API) manufacturing to prevent oxidation of sensitive compounds.
• Photographic Industry: Serves as a key component in developer and fixer solutions, acting as a preservative and stabilizing agent to extend shelf life.
• Textile Processing: Employed as a reducing agent and bleach stabilizer in dyeing and finishing processes to improve color fastness and fabric quality.
• Industrial Water Treatment: Functions as an oxygen scavenger in boiler feed water and closed-loop systems to prevent corrosion and scale formation.
• Chemical Synthesis: Utilized as a selective reducing agent in various organic synthesis reactions and as a stabilizer for peroxide-based formulations.
• Polymer & Resin Production: Acts as a polymerization modifier and stabilizer to control reaction rates and prevent premature degradation.

Quality Control

Our Trisodium Nitrilotrimethanesulphinate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting these results are provided as standard, ensuring full traceability and compliance with your quality assurance protocols.

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. For long-term storage, consider using an inert atmosphere to minimize oxidation.
