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


  • Evidence for HOOO radicals in the formation of alkyl hydrotrioxides (ROOOH) and hydrogen trioxide (HOOOH) in the ozonation of C-H bonds in hydrocarbons.: This research used tert-Butyl methyl ether to investigate the formation of hydrotrioxides and hydrogen trioxide in the ozonation of hydrocarbons, providing insights into radical chemistry and ozonation processes (Cerkovnik et al., 2002).

  • Determination of ochratoxin A in baby food by immunoaffinity column cleanup with liquid chromatography: interlaboratory study.: The study employed tert-Butyl methyl ether in the cleanup process for detecting ochratoxin A in baby food, demonstrating its effectiveness in ensuring food safety through reliable analytical methods (Burdaspal et al., 2001).

  • Sensitive high-performance liquid chromatography/mass spectrometry method for determination of steviol in rat plasma.: This paper highlights the use of tert-Butyl methyl ether in developing a sensitive HPLC/MS method for analyzing steviol in biological samples, showcasing its application in pharmacokinetic and toxicological studies (Wang et al., 2004).

  • Comparative fatty acid selectivity of lipases in esterification reactions with glycerol and diol analogues in organic media.: The research employed tert-Butyl methyl ether to investigate lipase selectivity in esterification reactions, illustrating its importance in biocatalysis and industrial applications of enzymatic processes (Lee & Parkin, 2000).

  • Analysis of coumarin 7-hydroxylation activity of cytochrome P450 2A6 using random mutagenesis.: This study utilized tert-Butyl methyl ether to analyze enzyme activity in cytochrome P450, demonstrating its utility in biochemical assays and the study of enzyme kinetics (Kim et al., 2005).
