Description

(2R,5R)-1-{[(2R,5R)-2,5-Diethylpyrrolidin-1-Yl]Methylene}-2,5-Diethylpyrrolidinium Tetrafluoroborate is a high-purity, chiral pyrrolidinium salt with a minimum assay of 97%, serving as a sophisticated organocatalyst precursor and chiral building block for advanced chemical synthesis. Its value lies in its defined stereochemistry and ionic nature, which are critical for inducing enantioselectivity in asymmetric transformations and for constructing complex molecular architectures. This compound is essential for R&D and production chemists in the pharmaceutical, agrochemical, and fine chemical industries who require high-performance, stereochemically pure intermediates.

Application

• Asymmetric Organocatalysis: As a precursor to chiral ionic liquids or catalysts for enantioselective C-C and C-X bond-forming reactions.
• Pharmaceutical Intermediate: Key chiral synthon in the synthesis of active pharmaceutical ingredients (APIs) requiring specific stereocenters.

Quality Control

Our (2R,5R)-1-{[(2R,5R)-2,5-Diethylpyrrolidin-1-Yl]Methylene}-2,5-Diethylpyrrolidinium Tetrafluoroborate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure it meets the specified minimum 97% purity and stereochemical integrity. A comprehensive Certificate of Analysis (COA) detailing identity, assay, impurity profile, and optical rotation is provided with each shipment to guarantee traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
