Product Overview
Dimethyl Sulphoxide (DMSO) 99.9% GC grade is a high-purity, aprotic solvent renowned for its ability to dissolve both polar and nonpolar compounds, making it indispensable in laboratory settings. This colorless, hygroscopic liquid exhibits low toxicity and exceptional thermal stability, ensuring reliable performance across diverse applications. Its unique molecular structure allows it to penetrate biological membranes, enhancing its utility in biochemical and pharmaceutical research. The 99.9% GC purity level guarantees minimal impurities, critical for sensitive analytical techniques and synthesis reactions. DMSO’s high boiling point (189°C) and miscibility with water and most organic solvents further expand its versatility. As a dipolar aprotic solvent, it facilitates SN2 reactions and stabilizes carbanions, while its cryoprotective properties make it valuable for cell preservation. The product’s consistent quality and batch-to-batch reliability meet stringent laboratory standards, ensuring reproducible results in critical experiments.
FAQs
1. What is the shelf life of DMSO 99.9% GC grade when stored properly?
When stored in tightly sealed original containers at room temperature, away from moisture and direct sunlight, DMSO 99.9% GC grade maintains its specified purity for 24 months from the date of manufacture.
2. Can this DMSO grade be used for NMR spectroscopy?
While DMSO-d6 is typically preferred for NMR applications, this 99.9% GC grade can be used for routine proton NMR when deuterated solvents are unavailable, though residual proton signals may appear in the spectrum.
3. What precautions should be taken when handling DMSO?
Always wear nitrile gloves, safety goggles, and work in a fume hood, as DMSO readily penetrates skin and can carry dissolved substances through biological membranes. Avoid plastic containers for long-term storage.
4. How does this compare to DMSO 99.7% or 99.5% grades?
The 99.9% GC grade offers significantly lower water content (<0.03%) and fewer organic impurities compared to lower grades, making it superior for applications requiring high purity like HPLC or sensitive organic syntheses.
5. What’s the typical moisture content in this DMSO grade?
This 99.9% GC grade DMSO contains less than 0.03% water by Karl Fischer titration, ensuring minimal interference in moisture-sensitive reactions and analytical procedures.
