Description

Potassium Hydrogen cis-Epoxysuccinate is a specialized organic salt derived from cis-epoxysuccinic acid. This compound is valued for its role as a versatile chiral building block and intermediate in fine chemical synthesis. It is particularly relevant for manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to produce optically active compounds.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in protease inhibitor development.
• Agrochemical Synthesis: Used in the production of chiral herbicides, fungicides, and plant growth regulators.
• Fine Chemical Production: Serves as a precursor for catalysts, ligands, and other high-value specialty chemicals.
• Biochemical Research: Employed in enzymatic studies and as a substrate or inhibitor in biochemical assays.
• Asymmetric Synthesis: Utilized in stereoselective reactions to introduce the cis-epoxysuccinate moiety into target molecules.
• Polymer Modification: Acts as a functional monomer or cross-linking agent for specialty polymers.

Quality Control

Our Potassium Hydrogen cis-Epoxysuccinate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets exacting standards for chemical and isomeric purity. Certificates of Analysis (COA) with detailed chromatographic data are provided for traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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 moisture absorption and potential degradation.
