Description

(-)-Tetraphos CAS NO 23582-04-9 is a chiral, tetradentate phosphine ligand widely recognized for its exceptional utility in asymmetric catalysis. Its value lies in its ability to induce high enantioselectivity in transition metal-catalyzed reactions, which is critical for producing optically pure compounds. This product is essential for researchers and process chemists in the pharmaceutical, agrochemical, and fine chemical industries who require precise stereochemical control in synthesis.

Application

• As a chiral ligand in asymmetric hydrogenation reactions for pharmaceutical intermediates.
• Catalyst component for enantioselective carbon-carbon bond formation (e.g., cross-coupling).
• Use in the synthesis of chiral active pharmaceutical ingredients (APIs) and agrochemicals.
• Key reagent for academic and industrial research in organometallic chemistry and catalysis.
• Employed in the production of specialty chemicals requiring specific stereochemistry.

Quality Control

Our (-)-Tetraphos is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chiral purity verification. A Certificate of Analysis (COA) detailing identity, purity, and chiral excess is provided with every shipment to meet the stringent requirements of research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry place. Due to its sensitivity to oxidation, the container should be purged with inert gas after each opening to maintain product integrity.
