Description

(Butylstannylidyne)Tris(Thioethane-1,2-Diyl) Tris[(9Z,12Z)-Octadeca-9,12-Dienoate] CAS NO 68928-37-0 is a specialized organotin compound featuring a central butylstannylidyne core linked to linoleate esters via thioether bridges. This unique molecular architecture makes it a valuable intermediate and catalyst precursor in advanced organic synthesis and polymer chemistry. It is primarily sought after by R&D chemists and process engineers in the fine chemical, pharmaceutical, and polymer additive industries for applications requiring precise metal-organic interactions.

Application

• Catalyst Precursor: Serves as a key starting material for synthesizing highly active tin-based catalysts used in esterification, transesterification, and polycondensation reactions.
• Polymer Stabilizer Intermediate: Used in the production of heat and light stabilizers for PVC and other halogenated polymers, enhancing material longevity.
• Crosslinking Agent: Facilitates the formation of thioether-linked networks in specialty silicone and rubber formulations, improving thermal and mechanical properties.
• Organic Synthesis Reagent: Employed in research laboratories for the selective introduction of tin-containing functional groups into complex organic molecules.
• Lubricant Additive Synthesis: Acts as an intermediate for creating multifunctional additives that provide anti-wear and extreme pressure properties.
• Surface Modification Agent: Used to functionalize material surfaces with organotin moieties for specific adhesion or catalytic properties.

Quality Control

Our production of (Butylstannylidyne)Tris(Thioethane-1,2-Diyl) Tris[(9Z,12Z)-Octadeca-9,12-Dienoate] adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, tin content, and impurity profiles are provided and available upon request to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong oxidizing agents.
