Product Overview
This anhydrous dimethylformamide (DMF) is a high-purity solvent with a maximum water content of 100 ppm, making it ideal for applications where moisture can compromise reaction integrity. The solvent undergoes rigorous purification processes to ensure consistent low-water specifications, providing reliability for sensitive chemical processes. Its high polarity and aprotic nature make it particularly effective for dissolving both polar and nonpolar compounds, while its thermal stability allows for use in elevated temperature reactions. The anhydrous grade eliminates the need for additional drying steps, saving time and reducing potential contamination risks. Packaged under inert conditions to maintain purity, this DMF variant is suitable for demanding laboratory environments where solvent quality directly impacts experimental outcomes. The 2.5L packaging offers an optimal balance between bulk efficiency and storage convenience for regular laboratory use.
FAQs
1. What is the typical shelf life of anhydrous DMF when stored properly?
When stored in its original sealed container under inert atmosphere and protected from moisture, the shelf life is typically 24 months from the date of manufacture.
2. How does the 100 ppm water specification compare to standard DMF grades?
Standard DMF typically contains 300-500 ppm water, while this anhydrous grade with ≤100 ppm offers significantly lower moisture content for applications requiring stringent dryness.
3. What type of container material is recommended for long-term storage?
Glass bottles with PTFE-lined caps are ideal for storage, as they prevent moisture ingress and are chemically resistant to DMF.
4. Are there any special handling precautions for this anhydrous grade?
Always handle under dry nitrogen or argon atmosphere to prevent moisture absorption, and use moisture-free transfer techniques when dispensing.
5. What analytical methods are used to verify the 100 ppm water specification?
The water content is typically verified using Karl Fischer titration, which provides precise measurement of trace moisture levels in solvents.
