Description

Ethyl (E)-3-Oxo-2-(2-Phenylhydrazono)Butanoate is a versatile organic intermediate characterized by its hydrazone and keto ester functional groups. This compound is valued for its role as a key building block in the synthesis of more complex heterocyclic and pharmaceutical molecules. It is primarily needed by research and development laboratories, fine chemical manufacturers, and pharmaceutical companies engaged in the production of active pharmaceutical ingredients (APIs) and specialty dyes.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of pyrazole and other nitrogen-containing heterocycles, which are core structures in many drug candidates.
• Agrochemical Synthesis: Used in the development of novel pesticides and herbicides, leveraging its reactive sites for constructing active molecules.
• Dye and Pigment Manufacturing: Serves as an intermediate for azo dyes and other colorants, where the phenylhydrazone moiety contributes to chromophore formation.
• Research & Development: Employed in academic and industrial R&D for exploring new organic reactions and creating libraries of novel chemical entities.
• Fine Chemical Production: Utilized as a specialized building block for custom synthesis and contract manufacturing of high-value chemicals.

Quality Control

Our Ethyl (E)-3-Oxo-2-(2-Phenylhydrazono)Butanoate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after the container has been opened.
