Description

2-Cyclopenten-1-Ol, 4-Phenyl-, (1R,4S)-Rel- (9Ci) is a chiral, non-racemic cyclopentenol derivative that serves as a valuable synthetic intermediate in advanced organic chemistry. Its defined stereochemistry and functionalized ring structure make it a critical building block for the stereoselective synthesis of complex molecules. This compound is primarily sought after by research and development teams in the pharmaceutical and fine chemical industries for applications in asymmetric synthesis and medicinal chemistry.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of active pharmaceutical ingredients (APIs), particularly in projects requiring stereochemical control.
• Asymmetric Synthesis: Used as a starting material or intermediate in catalytic asymmetric reactions to construct complex, enantiomerically pure compounds.
• Medicinal Chemistry Research: Employed in the design and synthesis of novel compound libraries for biological screening and structure-activity relationship (SAR) studies.
• Fine Chemical Production: Serves as a precursor in the multi-step synthesis of specialty chemicals, fragrances, and advanced materials where specific stereochemistry is required.
• Academic & Industrial R&D: A valuable reagent for methodological development in organic synthesis within university laboratories and corporate R&D centers.

Quality Control

Our production of this advanced chiral intermediate adheres to strict quality control protocols to ensure batch-to-batch consistency and high chemical purity, which is critical for sensitive synthetic applications. Identity, purity (typically assessed by chiral HPLC or GC), and enantiomeric excess are rigorously verified. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging.
