Description

Shi Epoxidation Catalyst, L-Enantiomer is a highly selective chiral catalyst designed for the asymmetric epoxidation of unfunctionalized olefins, enabling the production of enantiomerically pure epoxides. This catalyst is critical for achieving high enantiomeric excess (ee) in the synthesis of chiral intermediates, which are foundational building blocks for active pharmaceutical ingredients (APIs) and fine chemicals. It is essential for R&D and production chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require precise stereochemical control.

Application

• Asymmetric synthesis of chiral epoxides for pharmaceutical intermediates.
• Key catalyst in the production of enantiomerically pure β-blockers and other cardiovascular APIs.
• Chiral auxiliary in the synthesis of agrochemicals, such as herbicides and fungicides with specific stereochemistry.
• Research and development of novel chiral compounds in academic and industrial laboratories.
• Production of specialty chemicals and advanced materials requiring high optical purity.
• Scale-up processes for the manufacture of chiral flavors and fragrances.

Quality Control

Our Shi Epoxidation Catalyst, L-Enantiomer is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is characterized using advanced analytical techniques, including chiral HPLC and NMR spectroscopy, to confirm identity and assay. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and other critical parameters are provided with every shipment to support your quality assurance and regulatory needs.

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 material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment and handled under an inert atmosphere when appropriate to maintain stability and performance.
