Description and Specification


For Use With Sequencing and liquid chromatography applications
Formulation Clear, colorless liquid of dimethylsulfoxide (at least 99.5% pure; low water)
Item Name Pierce Dimethylsulfoxide (DMSO), Sequencing Grade
Quantity 950mL

A sequencing-grade preparation with high purity for use in traditional amino acid analyzers and other high-volume applications.

This sequencing-grade dimethylsulfoxide is >99.5% pure DMSO. The economically priced 950mL bottles are an excellent choice for protein and peptide applications that requiring large volumes of the water-miscible solvent. The 50mL bottles are provide convenience and minimize waste for small dissolution and reaction volumes. The purity test ensures that preparation is essentially devoid of amines. The formulation was originally developed for peptide sequencing applications with amino acid analyzers, which required high purity solvent and an affordable price. This DMSO is packaged in solvent-rinsed amber glass bottles and sealed with PTFE-lined fluorocarbon caps for ultimate protection.


  • High-purity (low amine) solvent for various protein, peptide and amino acid applications
  • Packaged in solvent-rinsed amber glass bottles and sealed with PTFE-lined fluorocarbon caps
  • Suitable for HPLC detection, although it is not specifically tested for low UV-absorptivity
