Description

Oxiranecarboxylic Acid, 3-Propyl-, Methyl Ester, cis- (9Ci) is a specialized, high-purity chemical intermediate characterized by its reactive oxirane (epoxide) and ester functional groups. This compound matters for its role as a versatile building block in advanced organic synthesis, enabling the introduction of both epoxide and ester moieties in a single molecule. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical and agrochemical industries for constructing complex molecular architectures, including active pharmaceutical ingredients (APIs) and novel crop protection agents.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs), particularly those requiring a cis-configured propyl-substituted glycidate framework.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides, where its epoxide ring can be opened to create new carbon-heteroatom bonds.
• Fine Chemical Production: Serves as a precursor for flavors, fragrances, and other specialty chemicals that benefit from its specific stereochemistry and functional group array.
• Polymer & Material Science: Acts as a monomer or cross-linking agent in the development of specialty polymers, resins, and coatings, utilizing the reactivity of the epoxide ring.
• Organic Synthesis Reagent: Employed in academic and industrial laboratories for stereoselective synthesis, asymmetric catalysis research, and method development.

Quality Control

Every batch of Oxiranecarboxylic Acid, 3-Propyl-, Methyl Ester, cis- (9Ci) is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure identity, purity, and consistency, meeting the exacting standards required for pharmaceutical and fine chemical applications. A Certificate of Analysis (COA) detailing specifications such as assay (by GC/HPLC), enantiomeric/excess, and impurity profiles is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
