Description

8-Ethyl-3-Propyl-1,5-Cyclononadiene-1,2,5,6-Tetracarboxylic Acid Tetrasodium Salt is a high-purity, water-soluble organic salt derived from a functionalized cyclononadiene core. This compound matters as a versatile chelating agent and intermediate for advanced chemical synthesis, offering excellent metal ion sequestration properties. It is primarily needed by manufacturers in the detergent, water treatment, and specialty polymer industries for formulating high-performance additives and complexing systems.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to inactivate water hardness ions (Ca²⁺, Mg²⁺), enhancing surfactant efficiency.
• Industrial Water Treatment: Used in scale and corrosion inhibition programs for cooling towers, boilers, and reverse osmosis systems.
• Chemical Synthesis Intermediate: Serves as a key precursor for synthesizing more complex macrocyclic ligands, polymers, and specialty surfactants.
• Textile Processing: Employed as a chelating agent in dyeing and bleaching baths to prevent metal-ion catalyzed degradation of fabrics and dyes.
• Pulp & Paper Manufacturing: Helps in peroxide stabilization and control of transition metal ions during bleaching processes.
• Personal Care Products: Can be formulated into high-end shampoos and cleansers as a conditioning and clarifying agent.
• Agricultural Formulations: Used in certain micronutrient fertilizers and pesticide products to improve stability and bioavailability.
• Laboratory Research: Utilized in academic and industrial R&D for studying coordination chemistry and developing new catalytic systems.
