Description

Methoxyacetic Acid CAS NO 625-45-6 is a versatile organic acid characterized by its methoxy-substituted acetic acid structure, serving as a valuable building block in advanced chemical synthesis. Its bifunctional nature, containing both a carboxylic acid and an ether group, makes it a critical intermediate for producing high-value specialty chemicals and functional materials. This compound is essential for manufacturers in the pharmaceutical, agrochemical, and polymer industries seeking to introduce specific solubility and reactivity profiles into their final products.

Application

• Pharmaceutical Intermediate: Key starting material or intermediate in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring ether-linked side chains for enhanced bioavailability.
• Agrochemical Synthesis: Used in the production of herbicides, pesticides, and plant growth regulators, where it acts as a precursor for esters and amides with specific biological activity.
• Polymer & Resin Modifier: Employed as a monomer or co-monomer to create specialty polymers, coatings, and adhesives with tailored properties like flexibility, adhesion, and chemical resistance.
• Chemical Research & Development: A valuable reagent in organic synthesis laboratories for constructing complex molecules, particularly in medicinal chemistry and material science projects.
• Solvent & Processing Aid: Functions as a specialty solvent or processing aid in specific formulations and chemical reactions due to its polar aprotic nature.
• Electrolyte Additive: Investigated for use as an additive in battery electrolytes to improve stability and performance in energy storage systems.

Quality Control

Our Methoxyacetic Acid is produced under a strict quality management system to ensure batch-to-batch consistency and reliability. We employ advanced analytical techniques, including Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC), to verify purity and identify impurities. Certificates of Analysis (COA) detailing specific batch results are provided with every shipment, and our quality systems support compliance with cGMP and ISO 9001 standards for industrial and fine chemical applications.

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). Keep away from heat sources, open flames, and incompatible materials such as strong bases and oxidizing agents. The container must be kept tightly sealed when not in use to minimize exposure to atmospheric moisture.
