Description

Sodium Tributylstannolate is an organotin compound that serves as a versatile reagent and catalyst in organic synthesis. This compound matters for its unique ability to facilitate transesterification and condensation reactions, offering chemists a powerful tool for constructing complex molecules. Industries such as pharmaceuticals, agrochemicals, and polymer manufacturing need it for the development of active ingredients and specialty materials.

Application

• Catalyst for Transesterification Reactions: Used in the production of polyesters, polycarbonates, and biodiesel, enabling efficient conversion under mild conditions.
• Intermediate in Pharmaceutical Synthesis: Acts as a key building block for creating active pharmaceutical ingredients (APIs), particularly in reactions requiring selective tin-mediated transformations.
• Polymerization Aid: Employed as a catalyst or co-catalyst in the synthesis of specific condensation polymers and silicone-modified resins.
• Agrochemical Manufacturing: Utilized in the synthesis of certain pesticides and herbicides where organotin intermediates are required.
• Research & Development: A valuable reagent in academic and industrial R&D labs for exploring new synthetic methodologies and organometallic chemistry.
• Cross-Coupling Reactions: Can serve as a tin source in Stille-type cross-coupling reactions for forming carbon-carbon bonds.

Quality Control

Our Sodium Tributylstannolate is produced and tested under strict quality management protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as assay, identity, and impurity profiles. Our quality commitment aligns with cGMP principles where applicable, and we support compliance with global regulatory standards including REACH.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong acids and oxidizing agents.
