Description

α-Methoxyphenylacetic Acid Hemisodium Salt is a high-purity organic salt derivative of methoxyphenylacetic acid, serving as a critical chiral intermediate and building block in advanced chemical synthesis. Its value lies in providing a stable, readily soluble form of the parent acid, facilitating precise reactions in controlled environments. This compound is essential for research and production facilities in the pharmaceutical, agrochemical, and specialty chemical industries, where it is utilized in the development of active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key chiral building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for non-steroidal anti-inflammatory drugs (NSAIDs) and other therapeutic agents.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, leveraging its aromatic structure.
• Chemical Research: Serves as a standard or reagent in method development and organic synthesis studies within R&D laboratories.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances requiring high-purity aromatic intermediates.
• Asymmetric Synthesis: Utilized in reactions requiring chiral induction to produce enantiomerically enriched compounds.

Quality Control

Our α-Methoxyphenylacetic Acid Hemisodium Salt is manufactured under a quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters are available for every shipment. We can support development and production needs requiring adherence to cGMP or other specific quality standards.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
