Description

Copper Bis(p-Hydroxybenzenesulphonate) is an organometallic coordination compound where copper is complexed with two p-hydroxybenzenesulfonate ligands. This compound is valued for its unique combination of copper's catalytic and biocidal properties with the water-solubility and stability imparted by the sulfonate groups. It serves as a critical intermediate and functional additive for manufacturers in the polymer, textile, and specialty chemical industries seeking to incorporate copper's beneficial characteristics into their formulations.

Application

• Polymer Stabilizer & Additive: Acts as a light stabilizer, antioxidant, or catalyst in the production of specialty plastics and synthetic fibers.
• Textile & Fiber Treatment: Used in antimicrobial finishing for fabrics and as a catalyst in dyeing processes.
• Catalyst Precursor: Serves as a source of copper in homogeneous and heterogeneous catalytic reactions for organic synthesis.
• Wood Preservative Formulation: A key component in water-based preservative systems to protect against fungal decay and insect damage.
• Industrial Biocide: Incorporated into coatings, adhesives, and sealants to provide antimicrobial protection.
• Chemical Synthesis Intermediate: Used in the preparation of more complex copper-containing compounds and metal-organic frameworks (MOFs).
