Description

General description

ACS reagent grade.

Application

• Spectroscopic and quantum chemical analysis of Isonicotinic acid methyl ester.: Demonstrates the utility of spectroscopic methods combined with quantum chemical calculations, techniques potentially applicable to samples involving DMSO ( Shoba et al., 2015).


• Modification of gelatin by reaction with 1,6-diisocyanatohexane.: Investigates the chemical modification of proteins, potentially relevant for studies using DMSO as a solvent to facilitate such reactions ( Bertoldo et al., 2007).


• Characterization of O-acetyl-(4-O-methylglucurono)xylan isolated from birch and beech.: Describes the characterization of natural polymers, where DMSO could be used to dissolve and analyze similar substances ( Teleman et al., 2002).
