Description

3,5-Dioxa-9-Thia-4-Phosphanonadecan-1-Aminium, 4-Hydroxy-N,N,n-Trimeth Yl-10-Oxo-7-((1-Oxodecyl)Thio)-, Hydroxide, Inner Salt, 4-Oxide, (S)- is a specialized zwitterionic phosphine derivative, valued for its unique combination of a phosphine oxide head group and a long-chain thioester tail. This molecular architecture makes it a highly effective ligand and surface-active agent in advanced catalytic systems and material science applications. It is primarily sought by R&D and production teams in the pharmaceutical intermediates, specialty polymer synthesis, and nanotechnology sectors where precise molecular control is critical.

Application

• Catalytic Ligand in Cross-Coupling Reactions: Used as a sophisticated ligand for transition metal catalysts (e.g., Pd, Rh) in C-C and C-X bond-forming reactions for pharmaceutical API synthesis.
• Surface Modifier for Nanoparticles: Imparts stability and functionality to metal and semiconductor nanoparticles due to its phosphine oxide and thioester moieties.
• Stabilizer and Co-catalyst in Polymerization: Employed in controlled radical polymerization (e.g., ATRP) and other specialty polymer production processes.
• Intermediate for Advanced Surfactants: Serves as a key building block for synthesizing next-generation, task-specific surfactants with unique micellar properties.
• Chiral Auxiliary in Asymmetric Synthesis: The (S)- configuration allows its use in stereoselective transformations to produce enantiomerically enriched compounds.
• Corrosion Inhibitor Formulation: The long alkyl chain and polar head group contribute to formulations that protect metal surfaces in specialized industrial environments.

Quality Control

Every batch of this high-purity specialty chemical is produced and analyzed under strict quality management systems. We ensure compliance with relevant ICH guidelines for pharmaceutical intermediates and provide comprehensive analytical data. A detailed Certificate of Analysis (COA) is supplied with each shipment, reporting key parameters such as assay (HPLC), chiral purity, and identified impurities. Our GMP-compatible facilities allow for the production of material suitable for advanced research and scale-up projects.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep away from heat and incompatible materials. For long-term storage, consider refrigeration at 2-8°C.
