High-purity S-BINOL (99%) chiral ligand for enantioselective synthesis. Optically active, ideal for catalytic applications.
Price range: ₹700.00 through ₹9,100.00
Product Name – S-BINOL 99% For Synthesis
Quantity/Pack Size – 5 g, 25 g, 100 g
Form – Solid (Powder/Crystals)
Grade – 99% Purity
Application – Asymmetric synthesis, chiral catalysis
S-BINOL (1,1′-Bi-2-naphthol) at 99% purity is a high-performance chiral ligand widely used in asymmetric synthesis due to its exceptional enantioselectivity. This optically active compound serves as a key building block in catalytic systems, enabling precise control over stereochemistry in organic reactions. Its rigid, bidentate structure facilitates strong metal coordination, making it indispensable for applications requiring high enantiomeric excess. The high purity ensures minimal impurities, reducing side reactions and improving yield consistency. S-BINOL is particularly valued in transition-metal-catalyzed processes, where its chiral environment induces selectivity. The solid form (typically white to off-white powder or crystals) offers stability under standard lab conditions, though it should be stored under inert atmosphere to prevent oxidation. Compatible with common organic solvents, it dissolves readily in dichloromethane, THF, and toluene, allowing seamless integration into existing protocols. Whether used in ligand design or as a resolving agent, this grade guarantees reproducibility in research-scale syntheses.
1
The specific optical rotation for S-BINOL at 99% purity is typically [α]D²Ⱐ≈ -35° (c = 1, THF), though exact values may vary slightly based on batch and measurement conditions. 2
Yes, 99% purity S-BINOL is suitable for palladium-catalyzed asymmetric reactions, but pre-treatment (e.g., deprotonation with a base) may be required to generate the active ligand species. 3
Store in a tightly sealed container under argon or nitrogen at 2–8°C, protected from light and moisture to prevent degradation or racemization over time. 4
S-BINOL forms stable complexes with Lewis acids such as Ti(OiPr)â‚„, commonly used in enantioselective additions like the Sharpless asymmetric dihydroxylation. 5
Lower grades (e.g., 97% or 95%) exist but may compromise enantioselectivity; this 99% grade is optimized for high-precision synthesis where purity is critical.
