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". Click here for more information.

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.

Features and Benefits

Greener alternative for THF, diethyl ether, and MTBE

The aim of this study was to characterize the kinetics of metabolite formation of the phosphodiesterase type-5 (PDE5) inhibitors sildenafil and tadalafil by CYP3A4, CYP3A5, and CYP3A7 isoforms. The formations of N-desmethyl sildenafil and desmethylene tadalafil were examined using CYP3A
