Description

Cyclopentyl Methyl Ether (CPME) is a versatile, high-performance aprotic solvent with a favorable environmental and safety profile. Its unique combination of properties, including high volatility, excellent stability, and low water solubility, makes it a superior alternative to traditional ethers like THF and 1,4-dioxane in demanding chemical processes. This solvent is essential for manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking efficient, reliable, and greener reaction media for synthesis, extraction, and purification.

Application

• Pharmaceutical Synthesis: A preferred solvent for Grignard reactions, metal hydride reductions, and as a reaction medium in API manufacturing due to its stability against peroxides and ease of removal.
• Agrochemical Formulation: Used as a key solvent and co-solvent in the production of pesticides and herbicides, offering excellent solvency for active ingredients.
• Specialty Chemical Production: Employed in polymerization reactions, as a solvent for resins and coatings, and in various organometallic catalyzed processes.
• Extraction & Purification: Effective in liquid-liquid extraction processes and as a recrystallization solvent due to its selective solvency and low miscibility with water.
• Electrolyte Solvent: Investigated for use in lithium-ion battery electrolytes owing to its high stability and favorable electrochemical properties.
• Laboratory & R&D: A valuable solvent for research chemists in discovery chemistry and process development across multiple disciplines.

Quality Control

Our Cyclopentyl Methyl Ether is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including GC, Karl Fischer titration, and residue on evaporation, to ensure it meets the high-purity standards required for sensitive applications. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We support cGMP and ISO 9001 standards for pharmaceutical and industrial customers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 15-25°C. Keep away from strong oxidizing agents.
