Dimethyl Sulfoxide (DMSO), with the molecular formula (CH₃)₂SO and CAS No. 67-68-5, is an important solvent widely used in pharmaceuticals, electronics manufacturing, and chemical production. Because different industries require different purity standards, DMSO is typically classified into pharmaceutical grade, electronic grade, and industrial grade. The main differences lie in purity control, impurity limits, and application requirements.
Pharmaceutical-grade DMSO requires the highest level of purity and quality control. It is widely used in drug research, pharmaceutical synthesis, and cell cryopreservation. Impurities such as heavy metals, residual solvents, and microbial contamination must be strictly controlled. Advanced purification technologies and analytical methods, including gas chromatography (GC), are commonly used to ensure product safety and stability.
Electronic-grade DMSO is mainly used in semiconductor manufacturing, electronic materials processing, and precision cleaning. In these applications, even trace metal ions or particles can affect device performance. Therefore, electronic-grade DMSO requires strict control of metal ion content, moisture, and particulate impurities, often produced under highly controlled environments.
Industrial-grade DMSO is primarily used in organic synthesis,agriculture and chemical manufacturing. Although the purity requirements are slightly lower, stable quality and consistent performance are still essential for large-scale industrial reactions.
