General description

EMSURE grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE provides worldwide best and most extensive product specifications. We declare our EMSURE range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

Application


  • Construction of Polycarbonates with Pendant Multifunctional Groups via a One-Step CO2/Diepoxide Copolymerization Approach.: This study employs tetrahydrofuran (THF) as a solvent in the synthesis of multifunctional polycarbonates through CO2 copolymerization, demonstrating its utility in creating advanced materials with potential applications in environmental sustainability and polymer chemistry (Wu et al., 2024).
