Description

Benzene, 1-Fluoro-4-[(S)-Methylsulfinyl]- (9Ci) is a high-purity chiral organosulfur compound featuring a sulfinyl group and a fluorine substituent on a benzene ring. This specific stereochemistry and functional group combination make it a valuable and versatile advanced pharmaceutical intermediate (API) for asymmetric synthesis. It is primarily sought after by R&D and process chemistry teams in the pharmaceutical and agrochemical industries for the development of novel active ingredients.

Application

• Pharmaceutical Intermediate: A key chiral building block in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and other therapeutic areas.
• Agrochemical Synthesis: Used in the research and development of advanced pesticides and herbicides where the chiral center and fluorinated aromatic system can enhance biological activity.
• Ligand and Catalyst Precursor: Serves as a precursor for chiral ligands or catalysts used in asymmetric catalysis, enabling the production of enantiomerically pure compounds.
• Material Science Research: Investigated for the development of specialty polymers and liquid crystals, where the sulfinyl and fluorine groups can modify material properties.
• Organic Synthesis Reference Standard: Employed as a high-purity analytical standard for method development and quality control in chemical analysis.

Quality Control

Every batch of our Benzene, 1-Fluoro-4-[(S)-Methylsulfinyl]- (9Ci) is produced under strict quality management systems. We employ advanced analytical techniques including HPLC, GC, Chiral HPLC, and NMR to ensure identity, purity, and enantiomeric excess (ee) meet exacting customer specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Recommended long-term storage temperature is 2-8°C.
