Description

o-Allyl-n-Benzylcinchondinium Bromide is a high-purity, organocatalytic phase-transfer catalyst derived from the cinchona alkaloid family. This compound matters for its critical role in facilitating highly enantioselective chemical transformations, particularly in asymmetric synthesis. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for the production of chiral intermediates and active ingredients.

Application

• As a phase-transfer catalyst (PTC) in asymmetric alkylation and conjugate addition reactions.
• Enabling enantioselective synthesis of non-natural amino acids and other chiral building blocks for pharmaceutical APIs.
• Catalyzing stereoselective glycosylation reactions in carbohydrate chemistry.
• Use in the development of novel chiral ligands and catalyst systems.
• Facilitating scale-up processes in fine chemical and agrochemical manufacturing.
• Research and development of new asymmetric catalytic methodologies in academic and industrial laboratories.

Quality Control

Our o-Allyl-n-Benzylcinchondinium Bromide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral analysis, to ensure it meets the high standards required for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific impurity profiles is provided with every shipment.

Storage

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