Description

Diethyl Oxalacetate is a versatile organic ester compound, also known as diethyl 2-oxobutanedioate, with significant utility as a key synthetic intermediate. Its bifunctional structure, containing both ketone and ester groups, makes it a valuable building block for constructing complex molecules in fine chemical synthesis. This product is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to synthesize heterocyclic compounds, active pharmaceutical ingredients (APIs), and flavor/fragrance components.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of various heterocyclic compounds, including pyridines, pyrroles, and quinolones, which are core structures in many active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of certain herbicides, fungicides, and plant growth regulators, leveraging its reactivity to form complex molecular scaffolds.
• Fine Chemical Production: Serves as a building block for synthesizing specialty chemicals, dyes, and complex organic molecules in research and development.
• Flavor and Fragrance Industry: Employed in the synthesis of aroma chemicals and flavoring agents due to its ability to form esters and ketones with specific olfactory properties.
• Chemical Research: A valuable reagent in organic synthesis laboratories for studying condensation reactions, such as Knorr pyrrole synthesis, and developing new synthetic methodologies.
• Coordination Chemistry: Acts as a ligand or precursor for metal-organic complexes and catalysts in certain specialized chemical processes.

Quality Control

Our Diethyl Oxalacetate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for synthetic applications. Key parameters including identity, assay, and impurity profiles are verified. A Certificate of Analysis (COA) detailing these results is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources, open flames, and incompatible materials such as strong oxidizing agents, strong bases, and strong acids. The container should be kept tightly sealed when not in use to minimize moisture absorption and degradation.
