Description

Trisodium CAS NO 55171-84-1 is a versatile inorganic salt widely utilized in industrial and chemical synthesis processes. Its primary value lies in its role as a buffering agent, chelating agent, and a source of sodium ions in various formulations. This compound is essential for manufacturers and R&D facilities in sectors such as water treatment, detergent production, and specialty chemical manufacturing, where precise pH control and metal ion sequestration are critical.

Application

• Water Treatment: Acts as a scale inhibitor and sequestering agent in boiler and cooling water systems.
• Detergent & Cleaning Formulations: Serves as a builder to enhance cleaning efficiency by softening water and inactivating metal ions.
• Chemical Synthesis: Used as a buffering agent and a sodium source in various organic and inorganic synthesis reactions.
• Textile Processing: Employed in dyeing and finishing processes to control water hardness and improve dye uptake.
• Pulp & Paper Industry: Functions as a dispersant and chelant in bleaching and papermaking processes.
• Metal Surface Treatment: Used in electroplating and metal cleaning solutions for pH stabilization.

Quality Control

Our Trisodium is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Quality is verified through a series of analytical tests including assay, impurity profiling, and physical parameter checks. Certificates of Analysis (COA) documenting purity and compliance with relevant industrial specifications are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture.
