General description

EMPLURA® is our low-cost alternative to high-purity qualities. With EMPLURA we offer a range of solvents for a plurality of basic applications in non-regulated industries and for less demanding applications, preparative laboratory work and cleaning purposes. EMPLURA solvents provide adequate specifications with the most important parameters.

Application


  • A simple and efficient synthesis of 5-hydroxymethylfurfural from carbohydrates using acidic ionic liquid grafted on silica gel.: This study presents a novel method for synthesizing 5-hydroxymethylfurfural, where DMSO plays a critical role in enhancing the efficiency and selectivity of the reaction under mild conditions (Doan VTC et al., 2024).

  • Controlling Tin Halide Perovskite Oxidation Dynamics in Solution for Perovskite Optoelectronic Devices.: This paper discusses the role of DMSO in managing oxidation processes in tin halide perovskites, crucial for developing stable and efficient optoelectronic devices (Nazeeruddin MKK et al., 2024).

  • Preparation technology comparison and performance evaluation of different protein A affinity chromatographic materials.: Demonstrates the effectiveness of DMSO in optimizing the preparation and performance of chromatographic materials used in protein purification (Zhou LJ et al., 2024).

  • Application of copper (I) selective ligands for PET imaging of reactive oxygen species through metabolic trapping.: Highlights a novel application of DMSO in the development of copper (I) selective ligands for positron emission tomography (PET), enhancing imaging techniques used in medical diagnostics (Tada T et al., 2024).

Caution

Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.
