How DMSO Purity is Determined and Why It Matters

Dimethyl sulfoxide, commonly known as DMSO, is a versatile solvent used in various industrial, pharmaceutical, and laboratory settings. However, when you're in the market to buy DMSO pharmaceutical grade, it's essential to understand the significance of its purity. 

Determining the Purity of DMSO

  1. Spectroscopy: Spectroscopic methods, particularly nuclear magnetic resonance (NMR) and infrared (IR) spectroscopy, are commonly used to determine the purity of DMSO. These methods identify and quantify the presence of impurities based on their molecular vibrations or magnetic properties.

  2. Gas Chromatography (GC): GC separates components in a mixture and can detect impurities in pure DMSO. Peaks representing different components appear in the GC output, allowing analysts to identify any impurities and their concentrations.

  3. Water Content: Karl Fischer titration is an analytical method frequently used to measure the water content in DMSO, as water is a common impurity.


Why Purity Matters

DMSO is not just another solvent; it has unique properties that make it an invaluable asset in various applications. Here's why its purity is paramount:

  1. Pharmaceutical Applications: DMSO can enhance the skin's permeability, making it an vehicle for delivering drugs through the skin. If you're planning to buy DMSO pharmaceutical grade for such purposes, ensuring its purity is essential to prevent unwanted side effects or interactions with contaminants.

  2. Research and Laboratory Uses: Pure DMSO is a standard solvent in chemical reactions and biological assays. The presence of impurities can interfere with experimental results, leading to inaccuracies.

  3. Industrial Processes: In industrial settings, DMSO can act as a reaction medium. Impurities can adversely affect the efficiency and outcome of these processes.


What to Consider When Buying DMSO

Given the importance of DMSO purity, here are some tips to consider when determining the best DMSO to buy:

  1. Source and Grade: Always opt for a reputable supplier that guarantees pharmaceutical grade DMSO at 99.9%. This grade ensures that the DMSO is of the highest purity suitable for use.

  2. Certificate of Analysis: Always ask for a certificate of analysis (COA) when purchasing DMSO. The COA provides detailed information about the product's purity and any detected impurities.

  3. Price vs. Quality: While price is an essential factor, it should not come at the expense of quality. The best DMSO to buy is one that offers both affordability and assured purity.


Over the years, DMSO uses have expanded beyond being just a solvent. It has found applications in medicine for its anti-inflammatory properties, as a cryoprotectant in cell cultures, and even in alternative medicine. 

It's worth noting that while DMSO has several approved medical uses, the FDA does not endorse its use for many of the health benefits claimed by some sources. As with any product, especially those for therapeutic use, always ensure you're informed and consult with a medical professional.

In conclusion, DMSO purity is not just a number on a label; it's a testament to the solvent's safety, efficiency, and versatility. Whether you're in the pharmaceutical sector, research, or any field requiring DMSO, always prioritize purity. And when looking to buy DMSO pharmaceutical grade, arm yourself with knowledge, ensuring you get the best value for your money.
