Description

(S)-1-(2-Chlorophenyl)Ethanol is a high-value chiral intermediate and building block of significant importance in asymmetric synthesis. Its enantiopure form is critical for producing pharmaceuticals and agrochemicals with high stereoselectivity and efficacy. This compound is primarily sought after by research institutions and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries for developing active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs), particularly in central nervous system (CNS) and cardiovascular drug candidates.
• Agrochemical Synthesis: Used in the production of chiral pesticides and herbicides, where the specific (S)-enantiomer can provide enhanced biological activity and environmental safety.
• Ligand and Catalyst Preparation: Serves as a precursor for chiral ligands and organocatalysts used in asymmetric hydrogenation, alkylation, and other stereoselective transformations.
• Fine Chemical Building Block: Employed in the research and development of specialty chemicals, flavors, fragrances, and advanced organic materials requiring precise stereochemistry.
• Academic and Industrial R&D: A valuable reagent for methodological development in organic chemistry and process chemistry optimization within laboratory and pilot-scale settings.

Quality Control

Our (S)-1-(2-Chlorophenyl)Ethanol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure compliance with exacting standards for enantiomeric excess (ee) and chemical purity. A Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to exclude moisture. Keep away from heat, sparks, and open flame.
