Description

Potassium Bisnonafluoro-1-Butanesulfonimidate is a high-value, specialty fluorinated salt with unique chemical properties derived from its perfluorobutylsulfonimidate anion. This compound is prized for its role as a key intermediate and reagent in advanced synthetic chemistry, particularly where the introduction of highly fluorinated groups is required. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors seeking to develop novel compounds with enhanced stability and performance characteristics.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), especially for introducing fluorinated motifs that can improve metabolic stability and bioavailability.
• Agrochemical Synthesis: Serves as a building block for creating novel herbicides, fungicides, and insecticides with fluorinated components for increased efficacy and environmental persistence.
• Advanced Material Production: A key precursor in the development of specialty polymers, surfactants, and coatings that require oil-, water-, and stain-repellent (fluorinated) properties.
• Electrolyte Additive: Investigated for use in high-performance lithium-ion battery electrolytes to enhance conductivity and interfacial stability.
• Catalyst and Ligand Synthesis: Employed in the preparation of novel anionic ligands and catalysts for organometallic chemistry and polymerization processes.
• Organic Synthesis Reagent: Functions as a versatile reagent for nucleophilic fluorination or as a counterion to stabilize reactive cationic species in complex organic transformations.

Quality Control

Our Potassium Bisnonafluoro-1-Butanesulfonimidate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and ion chromatography, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your R&D and production quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. Keep away from strong bases and incompatible materials.
