DMSO Anhydrous

DMSO Anhydrous Grade is Dimethyl Sulfoxide with an extremely low moisture content, produced under exacting manufacturing conditions to ensure dryness.

In certain analytical methods, water offers unwanted interference and can provide spurious information. This is especially true in IR Spectroscopy, wherein a small amount of water can obscure a large portion of the spectrum. In synthesis, DMSO Anhydrous Grade contains less than 50 ppm water, and minimizes losses to side reactions.

Key Applications for DMSO Anhydrous Grade

  • Compound Library Management. DMSO Anhydrous Grade may be used to store materials for later testing. The low water levels minimize degradation that may occur through association with water and hydrolysis. Compounds also stay in solution better in dry DMSO.
  • Water-Sensitive Compound Synthesis. Water present in DMSO can react with strong bases such as sodium hydride, butyllithium, and alkoxides. This can result in lower yields, and byproduct formation.
  • Water-Sensitive Analytical Applications. The potent solvent strength of DMSO makes it a valuable medium for the analysis and characterization of difficult-to-dissolve compounds and polymers.

DMSO ACS Spectrophotometric

DMSO ACS–Spectrophotometric Grade is Dimethyl Sulfoxide that conforms to the American Chemical Society’s (ACS) 9th Edition Specifications for Reagent Chemicals.

In addition to the normal parameters related to purity, this monograph specifies maximum UV absorbance levels at five wavelengths. This grade is the preferred solvent for any form of UV spectrophotometric analysis, due to its guaranteed analytical clarity.

DMSO ACS –Spectrophotometric Grade

  • HPLC Mobile Phase Component. The low UV limits of DMSO ACS Spectrophotometric grade result in minimal interference when using UV detectors in HPLC. The polarity of DMSO can be used to modify the solvent strength of HPLC eluent in reverse phase mode.
  • General Purpose Analysis Solvent. The nearly universal solvent properties of DMSO allow it to effectively dissolve difficult materials, including many polymers and inorganic materials. DMSO ACS Spectrophotometric grade is suitable for general UV and visible spectrophotometry, IR spectroscopy, and all methods that demand solvent purity and low levels of UV absorbance.
  • Solvent for High Throughput Screening of Investigational Compounds. The analytical clarity of this product, along with the ability to readily dissolve a wide range of compounds, make this grade ideal for HTS applications.

DMSO ACS Reagent

ACS - Reagent Grade is Dimethyl Sulfoxide that conforms to the American Chemical Society’s (ACS) 9th Edition Specifications for Reagent Chemicals. It meets requirements for general solvent use, and is adequate for many basic applications.

Key Applications for DMSO ACS - Reagent Grade

  • Analytical Applications wherein UV absorption is not critical. DMSO ACS - Reagent grade may be used as a solvent for non-spectrophotometric methods of analysis. DMSO is miscible with water in all proportions, and is a useful solvent for gas chromatography.

DMSO Synthesis Grade

DMSO Synthesis Grade is produced to an exacting quality standard specifically for the synthesis of Active Pharmaceutical Ingredients (API). DMSO Synthesis Grade simplifies the manufacturing process by contributing minimal process impurities, while providing a predictably low moisture level.

It is the appropriate choice in any chemical synthesis where the final purity of the finished compound is critical.

Key Applications for DMSO Synthesis Grade

  • The Finest Active Pharmaceutical Ingredients. A highly pure reaction solvent provides a simpler impurity profile. This can reduce costs associated with impurity identification and make product purification easier.
