Dimethyl sulfoxide (DMSO) for DNA & Peptide synthesis is a high-purity, polar aprotic solvent widely used in peptide and oligonucleotide synthesis, as well as in preparative and analytical procedures in pharmaceutical and biochemical laboratories.
🏭⚗️ Production
The solvent is produced by high-purity synthesis and purification under strictly controlled conditions to remove water and impurities. It is then packaged in sealed, moisture-resistant containers to preserve its chemical integrity and ensure consistent performance in regulated laboratory and industrial environments.
🔬 Properties
Dimethyl sulfoxide is a clear, colorless to slightly yellow liquid with a mild odor. It is highly polar, fully miscible with water and most organic solvents, and chemically stable under normal storage conditions. Its high polarity and ability to solvate both polar and nonpolar compounds make it ideal for dissolving peptides, nucleotides, and other reagents used in DNA and peptide synthesis.
🧪 Applications
In pharmaceutical and analytical laboratories, dimethyl sulfoxide is used as a solvent for peptide and oligonucleotide synthesis reactions. It facilitates coupling reactions, dissolution of reagents and intermediates, and preparative chromatography. It is also applied in laboratory-scale reactions requiring high solvation power and chemical stability to ensure reproducible and high-purity results.
⚠️ Safety
Dimethyl sulfoxide can penetrate the skin and carry dissolved chemicals into the body, and it may cause irritation or toxicity upon prolonged exposure. It should be handled in a well-ventilated fume hood with gloves, protective eyewear, and lab coats. Containers must be stored tightly sealed in a cool, dry place, away from strong oxidizers and acids. Waste and empty containers should be disposed of according to laboratory hazardous waste regulations.
