Dimethyl Sulfoxide (DMSO), identified by CAS number 67-68-5, is a chemical compound celebrated for its exceptional and diverse properties. As a premier supplier of DMSO, we believe that a thorough understanding of its chemical characteristics is vital for procurement managers, research scientists, and formulation chemists who rely on this versatile solvent. Let's explore the key properties that make DMSO a staple in laboratories and industries worldwide.

At its core, DMSO is a polar aprotic solvent. This classification means it possesses a high dielectric constant and dipole moment, allowing it to dissolve ionic compounds and polar molecules effectively, yet it lacks a transferable proton. This characteristic is crucial for many organic reactions where protic solvents might interfere. Its ability to dissolve a vast range of substances – from polar and nonpolar organic compounds to many inorganic salts and gases – earns it the moniker of a 'universal solvent.' This broad solvency makes it invaluable for applications ranging from chemical synthesis to drug formulation and analytical testing. Many professionals actively seek high purity DMSO for research to leverage these unique solvency properties.

DMSO is a colorless, hygroscopic liquid, meaning it readily absorbs moisture from the air. This necessitates proper storage in airtight containers to maintain its purity and performance. Its thermal stability is also noteworthy; it has a relatively high boiling point (189°C) and can be used in processes requiring elevated temperatures, although precautions are needed to prevent decomposition at very high temperatures. Understanding these physical attributes is key when considering procurement and handling procedures.

When sourcing DMSO, it's important to specify the grade required. For industrial or laboratory use, obtaining industrial grade DMSO from a reputable dimethyl sulfoxide manufacturer ensures consistent quality. The price of DMSO is influenced by its purity, with higher grades commanding higher prices, reflecting the rigorous purification processes involved. Many businesses choose to buy dimethyl sulfoxide online from trusted suppliers who can provide certificates of analysis and technical data to verify product specifications.

The chemical reactivity of DMSO also warrants consideration. While generally stable, it can react vigorously with strong oxidizing agents, strong acids, and certain halides, potentially leading to hazardous situations. Therefore, understanding its compatibility with other chemicals in your process is essential. As a leading DMSO supplier in China, we are equipped to provide the necessary safety data and technical support to ensure the responsible and effective use of our products.

In conclusion, the unique chemical and physical properties of Dimethyl Sulfoxide – its polarity, aprotic nature, broad solvency, thermal stability, and hygroscopicity – make it an indispensable chemical. By understanding these characteristics, procurement professionals can make informed decisions and ensure they source the right grade of DMSO for their specific applications.
