Amino Acid Analysis: Aqueous Dimethyl Sulfoxide As Solvent for the Ninhydrin Reaction
Methyl Cellosolve (the monomethyl ether of ethylene glycol) has been widely used as the organic solvent in ninhydrin reagents for amino acid analysis; it has, however, properties that are disadvantageous in a reagent for everyday employment. The solvent is toxic and it is difficult to keep the ether peroxide-free. A continuing effort to arrive at a chemically preferable and relatively nontoxic ...

متن کاملQuantitation of the hydroxyl radical by reaction with dimethyl sulfoxide.
This investigation was conducted to validate the use of dimethyl sulfoxide (DMSO) as a quantitative molecular probe for the generation of hydroxyl radicals (HO.) in aqueous systems. Reaction of HO. with DMSO produces methane sulfinic acid as a primary product, which can be detected by a simple colorimetric assay. To evaluate this method for estimating total HO. production, we studied three mode...
متن کاملDimethyl sulfoxide, diethyl fumarate solution for high dose dosimetry
Background: Dosimetry is a fundamental part of the radiation processing industry. Aqueous inorganic dosimeters have been used for gamma radiation dosimetry such as standard ferrous sulfate dosimeter. The purpose of this study was to investigate the effect of gamma radiation on the diethyl fumarate DEF in dimethyl sulfoxide DMSO solution and its possible use in chemical dosimetry. Materials and ...
