Description

(R)-(-)-5,5',6,6',7,7',8,8'-Octahydro-3,3'-Di-T-Butyl-1,1'-Bi-2-Naphthol, Dipotassium Salt is a high-purity, chiral chemical reagent primarily used as a catalyst or ligand in asymmetric synthesis. Its value lies in its ability to induce high enantioselectivity in critical organic transformations, enabling the production of single-isomer pharmaceutical intermediates and fine chemicals. This product is essential for R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-performance chiral auxiliaries.

Application

• As a chiral ligand in asymmetric metal-catalyzed reactions, such as additions to carbonyl compounds.
• As a catalyst for enantioselective alkylation and phase-transfer catalysis (PTC) reactions.
• In the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs) and key intermediates.
• For the development of novel agrochemicals with specific stereochemical requirements.
• In academic and industrial research for methodological development in organic synthesis.
• As a resolving agent or chiral selector in analytical chemistry applications.

Quality Control

Our (R)-(-)-H8-BINOL Dipotassium Salt is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including chiral purity verification by HPLC. A Certificate of Analysis (COA) detailing identity, assay, enantiomeric excess, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) in a dry environment to prevent degradation. Keep away from strong acids.
