Description

1,2-Propanediol,3-(2-Ethoxyphenoxy)-,(R)-(9Ci) is a high-purity chiral chemical intermediate of significant commercial interest. This compound is valued for its specific stereochemistry, which is critical for producing enantiomerically pure active pharmaceutical ingredients (APIs) and advanced agrochemicals. It is primarily sought by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for use in asymmetric synthesis and process development.

Application

• Pharmaceutical Intermediate: A key chiral building block in the synthesis of enantiomerically pure drugs, particularly in central nervous system (CNS) and cardiovascular therapeutic areas.
• Agrochemical Synthesis: Used in the production of advanced, stereospecific pesticides and herbicides where biological activity is dependent on the correct molecular configuration.
• Asymmetric Catalysis Research: Serves as a valuable ligand precursor or chiral auxiliary in academic and industrial research for developing new catalytic processes.
• Specialty Polymer Modifier: Can be incorporated to impart specific chiral or functional properties into high-performance polymers and resins.
• Fine Chemical Production: Employed in the multi-step synthesis of complex fragrance and flavor ingredients requiring precise stereochemical control.

Quality Control

Our 1,2-Propanediol,3-(2-Ethoxyphenoxy)-,(R)-(9Ci) is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure it meets the stringent requirements for chiral intermediates. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and enantiomeric excess.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
