Understanding the chemical underpinnings of active ingredients is crucial for any B2B professional in the chemical industry. Copper Quinolate, known scientifically as copper-8-quinolinolate and bearing the CAS number 10380-28-6, is a compound whose efficacy as a fungicide and bactericide is directly tied to its unique chemical structure and properties. This article explores the chemistry behind Copper Quinolate, its mode of action, and how these characteristics translate into its diverse applications in agriculture and beyond.

Copper Quinolate is a coordination complex formed between copper ions (Cu²⁺) and 8-hydroxyquinoline, also known as oxine. The structure involves two molecules of 8-hydroxyquinoline chelating a single copper ion. This chelation process stabilizes the copper ion and influences its biological activity. The molecular formula is C₁₈H₁₂CuN₂O₂, with a molecular weight of approximately 351.85 g/mol. Its physical form is typically a dark grey to black solid, insoluble in water, which contributes to its protective barrier function on plant surfaces.

The mode of action of Copper Quinolate as a biocide is multifaceted. Primarily, the copper ions released from the complex interfere with vital cellular processes in target organisms, such as fungi and bacteria. Copper ions are known to disrupt enzyme systems by binding to sulfhydryl (-SH) groups, which are critical for the activity of many enzymes involved in respiration and metabolism. This disruption inhibits essential biological functions, leading to cell death. The quinoline moiety itself also contributes to the antimicrobial activity, potentially by interacting with cellular membranes or other cellular components.

In agricultural applications, this chemical action translates to effective control of a broad spectrum of plant pathogens. As a fungicide, it protects crops from diseases like blights, mildews, and leaf spots. Its non-systemic, protective nature means it forms a barrier on the plant surface, preventing fungal spores from germinating and penetrating the plant tissue. As a bactericide, it similarly disrupts bacterial metabolism, controlling diseases such as bacterial spot and fire blight. The effectiveness of Copper Quinolate as a seed treatment also relies on this chemistry, providing early protection to vulnerable seedlings.

Beyond agriculture, the biocidal properties of Copper Quinolate are leveraged in material preservation. Its use in wood treatment aims to prevent fungal decay and insect damage, extending the service life of timber. In antifouling paints, it acts to prevent the colonization of marine organisms on ship hulls. The controlled release of copper ions from the insoluble matrix is key to its long-lasting protective effect in these applications.

For businesses looking to utilize the protective capabilities of Copper Quinolate, understanding its chemical behavior is paramount. Sourcing high-purity Copper Quinolate from reputable manufacturers is essential to ensure the intended chemical interactions and biological activities are achieved. Companies seeking to buy this compound should consult detailed product specifications and supplier information to guarantee the quality and efficacy required for their specific applications.

In summary, the chemical structure and properties of Copper Quinolate underpin its potent biocidal activity. Its ability to chelate copper and disrupt enzymatic processes makes it a highly effective fungicide and bactericide, valuable for crop protection and material preservation. For those looking to purchase this versatile compound, understanding its chemistry and working with reliable suppliers is key to unlocking its full potential.
