Cyclopentyl methyl ether (CPME), also known as methoxycyclopentane, is hydrophobic ether solvent. A high boiling point of 106 °C (223 °F) and preferable characteristics such as low formation of peroxides, relative stability under acidic and basic conditions, formation of azeotropes with water coupled with a narrow explosion range render CPME an alternative to other ethereal solvents such as tetrahydrofuran (THF), 2-methyltetrahydrofuran (2-MeTHF), dioxane (carcinogenic), and 1,2-dimethoxyethane (DME).
C 2828 (OTTO) Cyclopentyl methyl ether, GR 99%+ Cas 5614-37-9 - used in organic synthesis, mainly as a solvent. However it is also useful in extraction, polymerization, crystallization and surface coating. Reactions involving alkali agents: nucleophilic substitutions of heteroatoms (alcohols and amines).
