Description

8,8-Didodecyl-1,4-Dioxa-7,9-Dithia-8-Stannacycloundecane-5,11-Dione is a specialized organotin compound featuring a unique macrocyclic structure, which is critical for its function as a high-performance stabilizer and catalyst. This compound matters because it offers exceptional thermal and light stability, making it a key additive for protecting sensitive materials from degradation. It is primarily needed by manufacturers in the polymer industry, particularly for PVC stabilization, and by researchers developing advanced catalytic systems and functional materials.

Application

• Primary Stabilizer for PVC: Used as a highly effective heat and light stabilizer in the production of rigid and flexible polyvinyl chloride (PVC) products, including pipes, profiles, and films.
• Polymer Additive: Functions as a co-stabilizer or synergist in combination with other metal soaps to enhance the overall weathering resistance and longevity of polymer formulations.
• Catalyst Precursor: Serves as a precursor or catalyst in specific organic synthesis reactions, particularly those involving tin-mediated transformations.
• Material Science Research: Utilized in R&D for developing novel organometallic frameworks, functional coatings, and advanced polymeric materials with tailored properties.
• Lubricant and Grease Additive: Employed as an additive to improve the extreme pressure (EP) and anti-wear performance of industrial lubricants and greases.

Quality Control

Our 8,8-Didodecyl-1,4-Dioxa-7,9-Dithia-8-Stannacycloundecane-5,11-Dione is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay by titration or HPLC and identification by FT-IR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications 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 place at room temperature (15-25°C/59-77°F). Due to its sensitivity to light and tendency for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flames.
