DMSO: An Extraordinary Substance with Over 150 Years of Fascinating History

Dimethyl sulfoxide is an organic sulfur compound with the chemical formula C₂H₆OS. Pure DMSO is a clear, colorless, and largely odorless liquid at room temperature.

Chemists value DMSO as a polar aprotic solvent. Simply put, it can dissolve numerous substances that are difficult to dissolve in water or conventional organic solvents. Consequently, DMSO remains a staple in laboratories, research facilities, and various technical manufacturing processes.

Another distinctive feature is its ability to penetrate biological membranes. In doing so, DMSO can also influence the absorption of other dissolved substances. It is precisely this property that made the substance of interest for pharmaceutical and medical research—while also explaining why purity and careful handling are particularly important.

The history of DMSO begins in 1866, when the Russian chemist Alexander Zaytsev synthesized the compound for the first time. His research results were published the following year.

Initially, DMSO remained primarily a chemical specialty. It was only many decades later that it was realized how versatile the substance actually is. In the 1940s and 1950s, scientists increasingly focused on their extraordinary solvent properties.

During this time, DMSO was obtained, among other things, in the wood and paper industry. The starting point was sulfur-containing by-products of pulp production. Today, DMSO is mainly produced using modern chemical manufacturing processes and then processed and purified for the respective intended use.

In the 1950s, another remarkable property of DMSO was discovered: the substance can protect certain cells and biological tissues from damage caused by ice crystal formation during freezing.

As a result, DMSO is still used today as a cryoprotectant for preserving specific types of cells. This property plays a significant role in fields such as cell biology, stem cell research, and medical research.

This is one of the lesser-known aspects of DMSO. While many people primarily associate the substance with its properties as a solvent, it also serves as a vital tool in modern laboratories for the long-term storage of biological samples.

In the early 1960s, DMSO increasingly became a focus of medical research. The American surgeon Dr. Stanley W. Jacob and the chemist Robert Herschler played pivotal roles in this development.

Their investigations focused particularly on DMSO's ability to penetrate the skin and other biological membranes. Its potential utility as a carrier substance for other dissolved compounds also attracted significant interest.

These discoveries sparked an unusually broad range of research activities. In the decades that followed, DMSO was studied in connection with numerous biological processes, including inflammation-related mechanisms, oxidative stress, tissue protection, pain perception, and the absorption of other active substances.

Not every application investigated scientifically ultimately resulted in an approved medication. Nevertheless, the wide scope of these studies illustrates why DMSO continues to attract the interest of scientists, physicians, and informed users to this day.

A crucial distinction must be made regarding authorization: regulatory authorities do not grant a general authorization for a substance covering every conceivable use. A medicinal product authorization always applies to a specific preparation, a defined composition, a dosage form, and a precisely defined therapeutic indication.

Consequently, DMSO may be an ingredient in an authorized medicinal product in a given country without every over-the-counter DMSO product automatically being authorized as a medicine.

Not every use investigated scientifically has subsequently resulted in an authorized medicinal product. Nevertheless, the wide range of studies conducted illustrates why DMSO continues to attract the interest of scientists, physicians, and informed users.

A characteristic property of DMSO is its relatively high melting point of approximately 18°C. If the temperature drops below this level, the liquid may partially or completely crystallize.

Consequently, a bottle delivered in winter may be solid or contain visible crystals. This is a normal physical reaction and indicates neither contamination nor a quality defect.

If the sealed bottle is allowed to warm up slowly in accordance with the product instructions, the DMSO will revert to its liquid state. In principle, this common phase change does not compromise the quality of the product.

Not every scientifically investigated application has ultimately resulted in an approved medicinal product. Nevertheless, the wide range of studies conducted demonstrates why DMSO continues to attract the interest of scientists, physicians, and informed users alike.

DMSO can penetrate biological barriers and influence the absorption of other dissolved substances. Therefore, the product's purity, packaging, and handling require special attention.

When purchasing, one should look for the following features, among others:

• a clearly stated purity level,
• a transparent product specification,
• available batch and quality information,
• suitable packaging,
• a current safety data sheet,
• clear instructions regarding storage and handling.

Designations such as "technical grade," "laboratory grade," or "Ph. Eur." are not interchangeable. They represent different specifications and intended uses. A high percentage value alone does not indicate the test methods and limit values ​​used to evaluate the product.

The designation "Ph. Eur." indicates that the substance complies with the relevant monograph of the European Pharmacopoeia. This entails defined tests for identity, assay (content), and specified impurities, thereby defining a pharmaceutical quality specification.

DMSO is neither a fleeting discovery nor an ordinary everyday product. More than 150 years have passed since it was first synthesized. Over that time, the substance has established a firm place in organic chemistry, biological laboratories, cryopreservation, and select pharmaceutical products.

It is precisely this combination of a long history and remarkable versatility that makes DMSO so compelling to this day. Its unique properties open up a wide range of applications but also necessitate sound knowledge, clear product labeling, and responsible handling.

Anyone wishing to purchase DMSO should therefore look beyond the price alone. Quality, specifications, packaging, and transparent product information are at least as important.
