Product Name – CYCLOPENTYL METHYL ETHER (CPME) 99.9% AR Quantity/Pack Size – 500 ml, 1000 ml Form – Liquid Grade – AR (Analytical Reagent) Application – Solvent for organic synthesis, extractions, chromatography
Product Overview
CYCLOPENTYL METHYL ETHER (CPME) 99.9% AR is a high-purity, non-toxic solvent designed for demanding laboratory applications. With a boiling point of 101°C, it offers excellent thermal stability and low moisture absorption, making it superior to traditional ethers like THF or diethyl ether. The AR grade ensures minimal impurities, making it ideal for sensitive reactions, extractions, and chromatographic separations. CPME is widely recognized for its eco-friendly profile, as it is non-carcinogenic and biodegradable, reducing environmental impact without compromising performance. Its unique cyclic structure provides enhanced solubility for polar and non-polar compounds, ensuring versatility across various protocols. The solvent’s low peroxide formation risk further enhances safety during storage and handling. Whether used in organic synthesis, purification processes, or analytical techniques, CPME delivers consistent results with minimal residue. Its compatibility with a wide range of reagents and stability under varying conditions make it a reliable choice for modern laboratories. The 500 ml and 1000 ml pack sizes cater to both small-scale experiments and bulk requirements, ensuring convenience for researchers and educators alike.
FAQs
1. What is the boiling point of CPME 99.9% AR and why does it matter?
The boiling point of CPME is 101°C, which is higher than diethyl ether (34.6°C) but lower than water (100°C). This moderate boiling point allows for easier handling and evaporation control during reactions, reducing the risk of sudden vaporization while still enabling efficient solvent removal when needed. It also makes CPME safer to use in open systems compared to highly volatile ethers.
2. Can CPME replace THF or diethyl ether in existing protocols?
Yes, CPME can often replace THF or diethyl ether due to its similar solvating properties but with added advantages. Unlike THF, CPME does not form explosive peroxides upon storage, and unlike diethyl ether, it has a higher boiling point and lower flammability. However, slight adjustments to reaction temperatures or times may be required, as CPME’s polarity and boiling point differ from these solvents.
3. How should CPME 99.9% AR be stored to maintain its purity?
Store CPME in a tightly sealed, original container away from direct sunlight, heat sources, and ignition points. While it is more stable than other ethers, keeping it in a cool, dry, and well-ventilated area is recommended. Avoid prolonged exposure to air to prevent moisture absorption, though CPME is less hygroscopic than THF. No special inert gas storage is required, but ensuring the cap is securely closed after each use will preserve its purity.
4. Is CPME compatible with common laboratory plastics like PTFE or polypropylene?
CPME is generally compatible with most laboratory plastics, including PTFE, polypropylene, and HDPE, at room temperature. However, prolonged exposure or elevated temperatures may cause swelling or degradation in some polymers. For long-term storage or high-temperature applications, glass or PTFE-lined containers are preferred to avoid potential leaching or container failure.
5. What safety precautions should be taken when handling CPME?
While CPME is less hazardous than many traditional ethers, standard laboratory safety measures should still be followed. Use in a fume hood or well-ventilated area to avoid inhalation of vapors. Wear nitrile gloves, safety goggles, and a lab coat to prevent skin or eye contact. Though non-carcinogenic, it can cause mild irritation upon direct exposure. Keep away from open flames or sparks, as it is flammable, and have a Class B fire extinguisher nearby.
