How Is DMSO Solvent Used in Chemical Synthesis? -CAS 67-68-5

Dimethyl sulfoxide (DMSO) is a widely used solvent, miscible with water and many organic solvents.

DMSO was first discovered in the late 19th century as a byproduct of the wood pulp papermaking process. Around the same time, Russian chemist Alexander Zaitsev synthesized DMSO by oxidizing another byproduct of the kraft papermaking process-dimethyl sulfide. Zaitsev's synthesis method forms the basis of the DMSO production process still in use today.

How Is DMSO Solvent Used in Chemical Synthesis?

Dimethyl sulfoxide (DMSO) is commonly used as a reaction medium in organic chemistry because it dissolves a wide variety of reactants and remains effective even when conventional solvents fail.

As a polar aprotic solvent, DMSO stabilizes ions and is ideal for nucleophilic substitution, elimination, and base-catalyzed reactions, enabling faster and cleaner reactions.

DMSO can be used for mild oxidation reactions, converting alcohols to aldehydes or ketones without the need for potent reagents.

Dimethyl sulfoxide dissolves poorly soluble organic compounds, thereby improving reactant interactions and increasing synthetic conversion rates.

It is widely used in the manufacture of advanced materials, such as synthetic polymers, conductive materials, and specialty resins.

In industrial synthesis, DMSO chemicals are used for electrochemical reactions, battery research, and catalysis, improving ion transport and reaction stability.

The high boiling point of DMSO (CAS 67-68-5) (approximately 189°C) enables high-temperature reactions, reduces evaporation, and supports large-scale production.

DMSO solvent is stable and compatible with most acids, bases, catalysts, and reagents, making it suitable for complex synthesis.

Safety information

To ensure the quality and safety of DMSO chemicals:

• Store in a cool, dry, well-ventilated place.
• Keep away from strong oxidizers.
• Use airtight containers to prevent moisture absorption.
• Avoid skin contact (the substance can be absorbed through the skin).
