| sustainability | Greener Alternative Product |
| Application: | • Cyclopentyl methyl ether (CPME) is an alternative to ether solvents such as THF, diethyl ether, and MTBE with a higher resistance to peroxide formation. • The more environmentally conservative CPME solvent replaces hazardous solvents in order to achieve sustainability and reduce environmental and operational costs. • CPME offers considerable potential and advantage as a direct replacement for CH2Cl2 in binary eluents using MeOH as the modifier with MeOH–DMC and i-PrOH–EtOAc. |
| Application: | Green Alternative to THF, tert-Butyl methyl ether (MTBE), 1,4 Dioxane and other ether solvents The toxicological assessment of cyclopentyl methyl ether (CPME) as a green solvent. ![]() |
| Features and Benefits: | Greener alternative for THF, Diethyl ether, and MTBE |
| General description: | We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Cyclopentyl methyl ether (CPME) is a greener alternative to other ethereal solvents such as tetrahydrofuran (THF), 2-methyl tetrahydrofuran (2-MeTHF), dioxane (carcinogenic), tert-Butyl methyl ether (MTBE), and 1,2-dimethoxyethane (DME) and thus has been enhanced for "Safer Solvents and Auxiliaries".
