Dimethyl Sulfoxide (Spectranalyzed), Fisher Chemical

Description

Designed for optical analytical techniques, this Spectranalyzed grade dimethyl sulfoxide (DMSO) is supplied by Fisher BioReagents. The 1-liter quantity is packaged in an amber glass bottle, which provides protection against photodegradation to maintain the solvent's spectral properties. With the chemical identifier CAS 67-68-5 and a formula weight of 78.13 for C2H6OS, the solvent undergoes specific testing for characteristics like UV absorbance. This certification makes it suitable for applications in spectrophotometry, fluorescence spectroscopy, and other methods where trace impurities in the solvent could lead to significant background interference and inaccurate readings. The grade is selected for experiments where the spectral purity of the solvent matrix is as important as the analyte being measured.
