Thermo Scientific Pierce Dimethylsulfoxide (DMSO) is 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 50 mL bottles provide convenience and minimize waste for small dissolution and reaction volumes. (For protein and peptide applications that require large volumes of the water-miscible solvent, consider the related, economically-priced 950 mL bottles of DMSO, Cat. No. 20688.) 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.

Features of DMSO:

• 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
