Description

(1S)-1-(3-Chlorophenyl)Ethanol is a high-purity chiral intermediate of significant importance in advanced organic synthesis. Its defined stereochemistry makes it a critical building block for the production of enantiomerically pure pharmaceuticals and agrochemicals. This compound is essential for research and development chemists and process scale-up teams in the fine chemical and life sciences industries seeking reliable, high-quality chiral synthons.

Application

• Key chiral intermediate in the synthesis of active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and cardiovascular drugs.
• Building block for the development of novel agrochemicals, including herbicides and fungicides with specific stereochemical requirements.
• Starting material or resolving agent in asymmetric synthesis and catalysis research within academic and industrial R&D laboratories.
• Precursor for the manufacture of liquid crystals and other advanced materials where optical purity is crucial.
• Used in the preparation of specialty fragrances and flavors that require specific enantiomeric forms.
