Description

Ethyl (Hydroxyimino)Cyanoacetate Potassium Salt is a versatile organic salt primarily used as a key synthetic intermediate in advanced chemical manufacturing. Its value lies in its reactive functional groups, which enable the construction of complex heterocyclic and pharmaceutical scaffolds. This compound is essential for research and production chemists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of various drug candidates, particularly those containing pyrazole, isoxazole, and other nitrogen-containing heterocycles.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, contributing to the development of new crop protection agents.
• Dye and Pigment Manufacturing: Serves as a precursor for certain complex organic dyes and colorants, especially azo dyes and photochromic materials.
• Chemical Research & Development: A valuable reagent in organic synthesis laboratories for method development and the creation of novel chemical entities.
• Coordination Chemistry: Can act as a ligand or precursor for metal-organic frameworks (MOFs) and other coordination compounds due to its cyano and hydroxyimino groups.

Quality Control

Our Ethyl (Hydroxyimino)Cyanoacetate Potassium Salt is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for use in sensitive applications like pharmaceutical synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
