What is DMSO 99.9% (CAS:67-68-5) ?
Dimethyl sulfoxide (DMSO, CAS: 67-68-5) is an organic compound that serves as a common solvent and pharmaceutical carrier. Its chemical formula is (CH₃)₂SO, featuring one sulfur atom and two methyl groups. DMSO is a colorless, odorless liquid that remains transparent at room temperature.
Uses of DMSO 99.9% Pure Pharmaceutical Grade
Pharmaceutical Grade Dimethyl Sulfoxide (DMSO) is used primarily as a solvent or vehicle in pharmaceutical formulations. Its role in drug delivery and formulation is critical due to its unique chemical properties. Here's a breakdown of its main uses:
Solvent for Active Pharmaceutical Ingredients (APIs)
DMSO can dissolve a broad spectrum of polar and non-polar compounds, making it valuable for preparing liquid drug formulations, especially when working with active ingredients that are difficult to dissolve in water.
Enhancer of Drug Absorption (Penetration Enhancer)
It is known for its ability to increase the permeability of biological membranes, helping active substances pass through the skin or mucosal layers more efficiently. This makes it a useful component in topical and transdermal delivery systems.
Cryoprotective Agent
In the preservation of cells, tissues, and vaccines, DMSO helps protect biological samples during freezing by reducing ice crystal formation. It is widely used for long-term storage and transport of sensitive materials.
Stabilizer in Injectable Formulations
DMSO can help maintain the stability of certain injectable drugs by slowing down oxidation and other degradation pathways, ensuring the formulation remains effective over time.
Anti-inflammatory and Analgesic Use
Some topical preparations include DMSO for its soothing and pain-relieving effects, commonly used for muscle and joint discomfort. These applications are frequently seen in veterinary medicine, with limited but specific use in human products.
Component in Other Pharmaceutical Preparations
In ophthalmic solutions, it enables the dissolution of otherwise water-insoluble drugs. It is also incorporated into gels and creams to improve the penetration of active ingredients.
Research and Laboratory Applications
DMSO is a standard solvent in biological experiments, widely used to prepare stock solutions for cell culture, drug screening, and pharmacological studies.
Veterinary Formulations
It is also applied in animal health products aimed at reducing inflammation, aiding recovery from injuries, and supporting joint care.
