Key Points/Overview

DMSO is a unique solvent that is stable at high temperatures and is relatively inert, making it ideal for various chemical reactions. It was initially discovered as a byproduct of the kraft process for paper manufacturing and has since been synthesized for various applications.

DMSO’s ability to penetrate human skin has led to its use in transdermal drug delivery systems. It has also been studied for its potential anti-inflammatory properties and its role in autoimmune arthritis.

Uses & Benefits

Industrial Applications

DMSO serves as a solvent for a wide range of substances, including gases, synthetic fibers, and natural products. It is also used in NMR spectroscopy due to its deuterated form.

Medical Applications

DMSO has been approved by the FDA for treating chronic interstitial cystitis. It has also been explored for its potential in transdermal drug delivery systems.

Recent Discoveries

Recent studies have shown that DMSO can serve as a useful C1 source in organic synthesis, particularly in the production of pyrazole derivatives, which may be valuable for drug development.

Safety Information

Consumer Exposure

DMSO is generally considered safe for use in many consumer products, but excessive exposure can lead to skin irritation and other minor health issues.

Occupational Exposure

In industrial settings, exposure to DMSO can occur through skin contact or inhalation. Proper safety measures, including the use of Personal Protective Equipment (PPE), are essential.

When working with DMSO, it’s crucial to adhere to safety guidelines to minimize risks. Proper ventilation is essential, and the use of appropriate Personal Protective Equipment (PPE) is advised.
