Description

Oxiranecarboxamide, 3-(1-Oxobutyl)-, cis- (9Ci) is a specialized organic compound featuring a reactive oxirane (epoxide) ring and an amide functional group. This unique molecular architecture makes it a valuable chiral building block and intermediate for synthesizing more complex molecules with high stereochemical purity. It is primarily sought by research and development teams in the pharmaceutical and fine chemical industries for applications in asymmetric synthesis and the development of active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of novel Active Pharmaceutical Ingredients (APIs), particularly for drugs requiring specific stereochemistry.
• Asymmetric Synthesis: Utilized as a building block in stereoselective organic reactions to construct complex molecules with defined three-dimensional structures.
• Fine Chemical Production: Serves as a precursor in the manufacture of specialty chemicals, agrochemicals, and advanced materials where its epoxide functionality can be selectively opened.
• Academic & Industrial Research: Used in chemical research for method development, catalysis studies, and exploring new reaction pathways involving epoxides and amides.
• Ligand and Catalyst Development: Potential use in the synthesis of chiral ligands or organocatalysts for enantioselective transformations.

Quality Control

We maintain stringent quality control protocols for our fine chemical intermediates. Production follows current Good Manufacturing Practices (cGMP) where applicable, and each batch is analyzed to confirm identity, purity, and chiral integrity. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay (HPLC), enantiomeric excess, and impurity profiles is provided with every shipment to ensure traceability and compliance with your research or production requirements.

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 compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed and consideration should be given to storage under an inert atmosphere for long-term preservation of quality.
