Description

Tepa CAS NO 545-55-1 is a versatile organophosphorus compound known for its strong chelating and sequestering properties. This chemical is a critical intermediate and functional additive in numerous industrial processes where metal ion control is paramount. It is essential for manufacturers in sectors such as water treatment, textiles, and polymer production who require reliable performance and consistent quality. Our supply ensures high purity and stability for demanding applications.

Application

• Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water, boiler water, and reverse osmosis systems.
• Textile Processing: Used as a chelating agent to sequester metal ions during bleaching, dyeing, and finishing processes, improving color fastness and fabric quality.
• Polymer & Resin Production: Serves as a stabilizer and catalyst component in the synthesis of various polymers, including polyesters and polyamides.
• Pulp & Paper Industry: Enhances bleaching efficiency and protects equipment by chelating transition metals in pulp processing.
• Detergent & Cleaning Formulations: Functions as a builder to soften water and boost the cleaning power of industrial and institutional detergents.
• Metal Surface Treatment: Employed in electroplating and metal cleaning baths to control impurities and improve plating quality.
• Agriculture: Used in certain fertilizer and pesticide formulations as a stabilizing or complexing agent.
• Oilfield Chemicals: Applied as a component in drilling muds and production chemicals to control scale and corrosion.

Quality Control

Our Tepa is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, impurity profile, and physical property verification, to meet exacting customer specifications. Certificates of Analysis (COA) documenting purity, identity, and key parameters are provided with every shipment and are available 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 (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Keep away from strong bases and incompatible materials.
