Description

Phthalic Acid Mono-n-Butyl Ester Copper(Ii) Salt CAS NO 25215-53-6 is a specialized organometallic compound where copper is complexed with a phthalate ester ligand. This product serves as a critical catalyst and stabilizer in high-performance polymer synthesis and processing. It is primarily sought by manufacturers in the plastics, coatings, and specialty chemical industries for its unique reactivity and color properties.

Application

• Polymerization Catalyst: Acts as a catalyst or co-catalyst in the production of polyesters and other condensation polymers.
• PVC Stabilizer: Functions as a heat and light stabilizer in polyvinyl chloride (PVC) formulations to prevent degradation during processing and use.
• Antifouling Agent: Used in marine coatings and paints to inhibit the growth of algae and barnacles on ship hulls and underwater structures.
• Wood Preservative: Imparts fungicidal and insecticidal properties in treatments for lumber and wood products.
• Corrosion Inhibitor: Incorporated into protective coatings and lubricants for metals, particularly in industrial and marine environments.
• Specialty Pigment/Colorant: Provides a characteristic greenish-blue hue in certain plastics, inks, and artistic materials.
• Chemical Intermediate: Serves as a precursor for the synthesis of more complex organocopper compounds and coordination complexes.

Quality Control

Our production of Phthalic Acid Mono-n-Butyl Ester Copper Salt adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed for critical parameters including copper content, ester purity, and impurity profiles. Certificates of Analysis (COA) documenting these 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 room temperature (15-25°C). Keep away from strong acids and organic solvents. Due to its light-sensitive nature, containers should be opaque or stored in darkness.
