Product Overview
n-Dodecane, 99% anhydrous, is a high-purity linear alkane solvent designed for precision laboratory applications. Packaged under the AcroSeal® system, it guarantees minimal moisture contamination and extended shelf life, making it ideal for sensitive analytical procedures. This solvent exhibits excellent chemical stability, low UV absorbance, and a narrow boiling point range (215–217°C), ensuring consistent performance in gas chromatography (GC) and as a calibration standard. Its hydrophobic nature and low reactivity make it a preferred choice for extracting nonpolar compounds in organic synthesis. The anhydrous grade eliminates water interference, critical for accurate spectroscopic analysis and trace residue studies. Supplied in amber glass bottles to prevent photodegradation, this reagent meets stringent purity requirements for research-grade applications. Whether used as a mobile phase modifier or a reference material, its high evaporation rate and minimal residue formation enhance reproducibility in experimental workflows.
FAQs
1. What is the boiling point of n-Dodecane, and why does it matter?
The boiling point of n-Dodecane is 215–217°C. This high boiling range ensures it remains stable during heated analytical processes like GC, preventing premature evaporation and ensuring accurate separation of analytes.
2. Can this anhydrous grade be used for moisture-sensitive reactions?
Yes, the 99% anhydrous specification means water content is minimized to <0.01%, making it suitable for reactions where trace moisture could compromise results, such as Grignard reactions or organometallic synthesis.
3. How does AcroSeal® packaging improve solvent quality?
AcroSeal® packaging uses a hermetic seal with a PTFE-lined cap to block air and moisture ingress. This preserves the solvent’s purity by preventing oxidation or hydration during storage, even after multiple openings.
4. Is this n-Dodecane compatible with plastic labware?
While n-Dodecane is generally inert, prolonged contact may soften certain plastics like polyethylene or polypropylene. For long-term storage or reactions, use glass or PTFE-coated containers to avoid leaching or contamination.
5. What alternatives exist if n-Dodecane is unavailable?
For similar applications, n-Undecane (C11) or n-Tridecane (C13) can substitute, though their boiling points and polarity differ slightly. Isooctane or hexane may also work for less demanding solvent needs, but purity and anhydrous grades must match the application requirements.
