Description

(2-Butenyl)Tributylstannane is a specialized organotin compound of significant interest in advanced organic synthesis. Its core value lies in its utility as a versatile reagent for introducing the 2-butenyl (crotyl) group via palladium-catalyzed cross-coupling reactions, such as the Stille reaction. This makes it an essential building block for researchers and process chemists in the pharmaceutical and agrochemical industries developing novel active ingredients. The compound is also valuable in materials science for the preparation of functional polymers and precursors.

Application

• Pharmaceutical Intermediate Synthesis: A key reagent in Stille cross-coupling reactions for constructing complex molecular architectures in drug discovery and development.
• Agrochemical Production: Used to synthesize advanced crop protection agents by introducing the crotyl moiety into target molecules.
• Materials Science Research: Serves as a precursor for creating organotin-containing polymers and advanced materials with specific electronic or catalytic properties.
• Fine Chemical Manufacturing: Employed in the scalable synthesis of specialty chemicals and fragrances requiring selective alkylation.
• Catalysis Development: Acts as a model substrate or ligand precursor in the development of new catalytic systems.
• Academic & Industrial R&D: A fundamental tool for methodological studies in synthetic organic chemistry laboratories worldwide.

Quality Control

Every batch of (2-Butenyl)Tributylstannane is produced and analyzed under strict quality management protocols to ensure high purity and batch-to-batch consistency, which is critical for reproducible cross-coupling yields. Our standard quality control includes comprehensive analysis via NMR (¹H, ¹³C, ¹¹⁹Sn), GC, and elemental analysis. A detailed Certificate of Analysis (COA) providing full specification data is supplied with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to reach ambient temperature before opening to minimize moisture ingress.
