Description

Chlorodimethyl[(Trifluoroacetyl)Oxy]Stannane is a specialized organotin reagent featuring a reactive trifluoroacetoxy ligand. This compound is valued for its role as a versatile intermediate and catalyst in advanced synthetic chemistry, particularly for introducing tin and fluorine-containing functional groups. It is primarily sought by R&D chemists and process development teams in the pharmaceutical, agrochemical, and advanced materials sectors for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for constructing organotin-containing scaffolds or facilitating specific coupling reactions.
• Catalyst Precursor: Serves as a precursor for generating active tin-based catalysts used in polymerization, esterification, and transesterification reactions.
• Agrochemical Synthesis: Employed in the research and development of novel pesticides and herbicides where the tin moiety imparts specific biological activity or stability.
• Material Science Research: Utilized in the development of specialized polymers, coatings, and advanced materials that benefit from tin-fluorine chemistry.
• Cross-Coupling Reactions: Acts as a transmetalation agent or reactant in Stille-type cross-coupling reactions for carbon-carbon bond formation.
• Organic Synthesis Reagent: Functions as a trifluoroacetylating agent or a source of the dimethyltin group in complex multi-step synthetic pathways.

Quality Control

Our Chlorodimethyl[(Trifluoroacetyl)Oxy]Stannane is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including NMR (1H, 13C, 19F) and chromatographic methods, to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical properties is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and prevent decomposition. Recommended storage temperature is 2-8°C for long-term stability.
