Description

Tributyl(Pentachlorophenoxy)Tin is an organotin compound with the CAS number 3644-38-0, functioning as a specialized biocidal and chemical intermediate. This compound matters for its potent activity as a fungicide and wood preservative, offering targeted protection against microbial degradation. Industries requiring high-performance biocidal agents, such as wood treatment, marine antifouling paints, and industrial material preservation, are the primary users of this chemical.

Application

• Wood Preservative: Acts as a fungicide and insecticide in pressure-treated lumber and timber products for long-term protection against rot and pests.
• Marine Antifouling Agent: A key component in specialized coatings for ship hulls and underwater structures to prevent the growth of barnacles, algae, and other marine organisms.
• Industrial Biocide: Used in cooling water systems, pulp and paper mills, and other industrial processes to control microbial growth and biofouling.
• Agricultural Fungicide: Employed in specific agricultural formulations for protecting crops and stored materials from fungal diseases.
• Chemical Synthesis Intermediate: Serves as a precursor or reagent in the synthesis of other organotin compounds and specialty chemicals.
• Material Protection: Incorporated into plastics, textiles, and sealants to impart fungicidal and bactericidal properties, extending material lifespan.

Quality Control

Our Tributyl(Pentachlorophenoxy)Tin is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity, consistent composition, and performance as a biocidal agent. While specific grades may vary, our standard quality commitment includes verification of identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure full traceability and compliance with your specifications.

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 degradation from atmospheric moisture. Keep away from strong alkalis and incompatible materials. Store separately from food and feedstuffs.
