DMSO ACS Reagent Grade Product Sheet

The Perfect Choice for the Laboratory

DMSO ACS Reagent Grade is Dimethyl Sulfoxide which conforms to the American Chemical Society’s (ACS) 9th Edition Specifications for Reagent Chemicals. It meets requirements for general solvent use and is adequate for many basic applications.

Representative Specification

General Solvent Cleaning Applications
DMSO is an effective solvent for removing organic materials from equipment lines and manufacturing equipment. DMSO exhibits high solubility for many polymers and may aid in polymer processing and clean-up.


Chemical Process Development
When a process is scaled up on its way to commercialization, a reagent grade solvent is often sufficient for examining manufacturing variables. DMSO ACS Reagent grade may be an economical option for such testing.


Analytical Applications wherein UV absorption is not critical
DMSO ACS Reagent grade may be used as a solvent for non-spectrophotometric methods of analysis. DMSO is miscible with water in all proportions and is a useful solvent for gas chromatography.
