Import Binap — Buy in Bulk from Supplier in India

Binap (2,2'-bis(diphenylphosphino)-1,1'-binaphthyl) is a chiral diphosphine ligand widely employed in asymmetric catalysis, supplied here as its ruthenium(II) diacetate complex with CAS number 325146-81-4. The molecular formula C48H38O4P2Ru yields a molecular weight of 841.85 g/mol, and the compound is catalogued under MDL number MFCD09753020. This coordination compound pairs the atropisomeric (R)-BINAP backbone with a ruthenium centre stabilised by two acetate ligands, making it suitable for hydrogenation and related stereoselective transformations. Synonyms include diacetato[(R)-(+)-2,2'-bis(diphenylphosphino)-1,1'-binaphthyl]ruthenium(II), reflecting its precise structural identity for procurement and regulatory documentation.

The ligand scaffold consists of two diphenylphosphino groups appended to a 1,1'-binaphthyl core, with the (R)-enantiomer conferring defined stereochemical bias in catalytic cycles. Ruthenium(II) sits in a pseudo-octahedral environment with the bidentate phosphine and two monodentate acetate ligands completing the coordination sphere. Typical commercial batches for asymmetric hydrogenation catalysts are supplied with specified enantiomeric excess above 99 percent and metal content confirmed by ICP-MS or similar trace analysis. Standard storage requires inert atmosphere (nitrogen or argon) at 2-8 degrees Celsius to prevent oxidation of the phosphine donors and hydrolytic degradation of the acetate bridges.

This complex finds primary application in catalytic asymmetric hydrogenation of functionalised olefins, ketones and imines in pharmaceutical and fine chemical manufacture. Buyers include custom synthesis houses, API producers and academic research groups requiring enantioselective route development. The supplier, Synthesis With Catalysts Pvt. Ltd., is located in Sahibabad, Uttar Pradesh, a region with established chemical manufacturing infrastructure. Importers should confirm batch-specific certificates of analysis, metal assay and residual solvent content before committing to bulk orders, as catalyst performance depends critically on ligand integrity and metal oxidation state.

Synthesis With Catalysts Pvt. Ltd. is registered at 40/1B/6, Sahibabad, Uttar Pradesh 201010, India, operating within the National Capital Region's chemical manufacturing corridor. The supplier holds a harbour trust tier on the platform, with a response rate of 0.00 percent and zero average response hours recorded, indicating no historical transaction data or unresponsive communication channels. The listing presents solely product-level technical data without disclosure of manufacturing capacity, quality management system certifications, or export licence details. Buyers should therefore verify GMP compliance, ISO certification status and analytical capabilities directly with the supplier before qualification.

The company specialises in catalyst and ligand supply for asymmetric synthesis, as inferred from its product focus and corporate name. No employee count, annual turnover, client references or years in operation are stated in the available profile. The absence of response metrics suggests either a new listing or dormant account, making direct technical dialogue essential before order placement. Importers are advised to request a supplier questionnaire, audited financials and references from comparable chemical procurement engagements to assess reliability.
