Description

(11Bs)-4,4-Dibutyl-4,5-Dihydro-2,6-Bis[3,5-Bis(Trifluoromethyl)Phenyl]-3H-Dinaphtho[2,1-C:1′,2′-E]Phosphepinium Bromide CAS NO 1110711-01-7 is a high-value, organophosphorus salt characterized by its complex, sterically hindered structure and the presence of electron-withdrawing trifluoromethyl groups. This compound is a critical specialty chemical intermediate and catalyst precursor, prized for its role in facilitating challenging organic transformations. It is primarily sought by R&D and process development teams in the pharmaceutical and advanced materials sectors for synthesizing novel active ingredients and functional molecules.

Application

• Catalyst Precursor: Serves as a key ligand or cationic component in the development of advanced transition metal catalysts for cross-coupling reactions (e.g., Suzuki, Heck).
• Pharmaceutical Intermediate: Used in the research and synthesis of complex drug candidates, particularly where fluorinated aromatic systems are required for metabolic stability.
• Organic Synthesis Reagent: Employed as a specialized reagent or building block in academic and industrial laboratories for constructing intricate polycyclic frameworks.
• Materials Science Research: Investigated as a potential component in the development of novel ionic liquids, electrolytes, or photoactive materials due to its unique cationic structure.
• Asymmetric Synthesis: Its chiral, bulky structure makes it a candidate for use in designing chiral auxiliaries or catalysts for enantioselective transformations.

Quality Control

Every batch of this high-purity specialty chemical is produced and analyzed under strict quality protocols. We provide comprehensive Certificates of Analysis (COA) that detail identity, purity, and impurity profiles, ensuring traceability and consistency for your critical research and development work. Our quality system is designed to meet the stringent requirements of cGMP and ISO standards for advanced chemical intermediates.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials.
