Description

[S(R)]-n-[(S)-[2-(Diphenylphosphino)-4,5-Dimethoxyphenyl)](4-Methoxyphenyl)Methyl]-N,2-Dimethyl-2-Propanesulfinamide CAS NO 2565792-80-3 is a sophisticated chiral sulfinamide-phosphine hybrid ligand, representing a high-value specialty chemical for advanced synthetic chemistry. Its core value lies in enabling highly selective asymmetric transformations, crucial for producing enantiomerically pure intermediates in pharmaceutical and fine chemical synthesis. This compound is essential for R&D scientists and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require precise stereocontrol in catalytic reactions such as asymmetric hydrogenations and cross-couplings.

Application

• As a chiral ligand in transition metal-catalyzed asymmetric synthesis, including hydrogenation and C-C bond formation.
• For the development of enantioselective catalytic processes in pharmaceutical active ingredient (API) manufacturing.
• In academic and industrial research for exploring new methodologies in organometallic chemistry and catalysis.
• As a key building block or catalyst component for the synthesis of complex natural products and chiral agrochemicals.
• For process optimization and scale-up in fine chemical production, where high enantiomeric excess (ee) is critical.

Quality Control

Every batch of this high-purity chiral ligand is subjected to rigorous analytical testing, including HPLC, NMR, and chiral analysis, to ensure identity, purity, and enantiomeric integrity. We adhere to strict internal specifications aligned with the needs of advanced chemical synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and chiral purity is provided with each shipment to guarantee batch-to-batch consistency and support your quality documentation.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C or as specified on the label. Due to its sensitivity, the container should be allowed to reach room temperature before opening to minimize moisture ingress and oxidative degradation. Keep away from strong oxidizing agents.
