Description

Oxiranecarboxylic Acid, 3,3-Dimethyl-, Ethyl Ester, (+)- (9Ci) CAS NO 134275-33-5 is a high-purity, chiral epoxide derivative valued for its role as a versatile synthetic building block in advanced organic synthesis. Its defined stereochemistry and reactive oxirane ring make it a critical intermediate for constructing complex molecules with high enantiomeric purity. This compound is essential for research and production in the pharmaceutical and fine chemical industries, where precise molecular architecture is required.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in routes requiring enantioselective epoxide ring-opening reactions.
• Agrochemical Synthesis: Used in the production of chiral pesticides, herbicides, and plant growth regulators where biological activity is stereospecific.
• Ligand and Catalyst Preparation: Serves as a precursor for synthesizing chiral ligands and organocatalysts used in asymmetric catalysis.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances that require enantiomerically pure epoxide intermediates.
• Polymer Modification: Can be used to introduce reactive epoxide functionalities into polymer chains for cross-linking or to create specialty resins.
• Academic and R&D: A valuable reagent in university and industrial research laboratories for methodological development in organic and medicinal chemistry.
