Description

Oxiranecarboxylic Acid, 3-Propyl-, Methyl Ester, (2R-Cis)- (9Ci) is a high-purity chiral epoxide derivative, a critical building block in advanced organic synthesis. This compound matters for its role as a versatile and stereochemically defined intermediate, enabling the precise construction of complex molecular architectures. Pharmaceutical, agrochemical, and specialty chemical manufacturers need it for the development of active ingredients and fine chemicals where chirality and functional group compatibility are paramount.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in routes requiring stereoselective ring-opening reactions.
• Agrochemical Synthesis: Used in the production of chiral pesticides, herbicides, and plant growth regulators where biological activity is enantiomer-specific.
• Ligand and Catalyst Preparation: Serves as a precursor for chiral ligands and organocatalysts used in asymmetric synthesis.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances requiring high enantiomeric purity.
• Polymer Modification: Can be used to introduce epoxy functional groups into polymer chains for cross-linking or to impart specific material properties.
• Academic and R&D: A valuable reagent for methodological development in organic chemistry and medicinal chemistry research programs.

Quality Control

Our Oxiranecarboxylic Acid, 3-Propyl-, Methyl Ester, (2R-Cis)- is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral HPLC for enantiomeric excess (ee) and standard purity assays, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) with full traceability are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent degradation.
