Description

Diglyme is a high-purity, aprotic polar solvent with excellent chemical stability and solvating power. Its unique properties make it an indispensable component in advanced chemical synthesis and specialized industrial processes. This product is essential for manufacturers in the pharmaceutical, electronics, and specialty chemical sectors requiring a reliable, high-boiling-point ether solvent for demanding applications.

Application

• Chemical Synthesis: A preferred solvent for Grignard reactions, borane reductions, and other organometallic processes where a non-nucleophilic, high-boiling-point ether is required.
• Electrolyte Formulation: Used as a co-solvent in lithium-ion battery electrolytes to enhance conductivity and stability.
• Polymer & Resin Production: Acts as a reaction medium and solvent in the production of polymers, resins, and specialty coatings.
• Gas Absorption: Employed as a selective solvent for gas scrubbing and purification processes in natural gas treatment.
• Pharmaceutical Manufacturing: Serves as a process solvent in various synthesis and purification steps for active pharmaceutical ingredients (APIs).
• Laboratory Research: A valuable reagent and solvent in research and development for organic chemistry and material science.

Quality Control

Our Diglyme is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed to meet precise specifications, with a focus on critical parameters such as assay, water content, and peroxide formation. Certificates of Analysis (COA) documenting full test results are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong oxidizing agents. Due to its hygroscopic nature, containers should be kept tightly sealed to prevent moisture absorption. Recommended storage temperature is between 15°C and 25°C.
