Product Overview
tert-Butyl methyl ether (MTBE) 99.8% PRA is a high-purity, anhydrous solvent widely used in laboratory settings for its excellent solvency properties and low reactivity. This pro-analysis (PRA) grade ensures minimal impurities, making it suitable for sensitive applications such as chromatography, extractions, and organic synthesis. The ether’s low boiling point (55°C) and high volatility facilitate quick evaporation, reducing residue formation in analytical procedures. Its miscibility with common organic solvents like ethanol, acetone, and hexane enhances its versatility in multi-solvent systems. The 99.8% purity level guarantees consistent performance in quantitative analyses, while its low water content (<0.01%) prevents interference in moisture-sensitive reactions. Packaged in a 1000 ml amber glass bottle, it is protected from light-induced degradation, preserving its stability during storage. This grade is particularly valued in gas chromatography (GC) and high-performance liquid chromatography (HPLC) for its UV transparency and minimal background noise, ensuring accurate peak detection. The chemical’s low viscosity and high diffusion rate further improve separation efficiency in chromatographic techniques. As a non-polar aprotic solvent, it effectively dissolves non-polar and moderately polar compounds without participating in hydrogen bonding, making it ideal for extracting lipids, essential oils, and other hydrophobic substances. Its compatibility with most labware materials, including glass and PTFE, minimizes contamination risks. For optimal results, store in a cool, well-ventilated area away from ignition sources, as MTBE is highly flammable.
FAQs
1. What is the shelf life of tert-butyl methyl ether 99.8% PRA when stored properly?
The shelf life is typically 24 months from the date of manufacture when stored in a tightly sealed container at room temperature, away from direct sunlight and moisture. Always check the label for the exact expiry date.
2. Can this grade of MTBE be used as a substitute for diethyl ether in extractions?
Yes, tert-butyl methyl ether is often preferred over diethyl ether due to its higher boiling point, lower peroxide formation risk, and better stability. However, compatibility with your specific extraction protocol should be verified.
3. Is this product compatible with plastic containers or tubing?
MTBE can degrade certain plastics, including polyethylene and PVC. Use glass or PTFE-lined containers and tubing to avoid contamination or leaks.
4. What precautions should be taken when handling tert-butyl methyl ether?
Wear nitrile gloves, safety goggles, and work in a fume hood due to its flammability and potential respiratory irritation. Avoid inhalation and skin contact, and keep away from open flames or sparks.
5. How does the PRA grade differ from technical or reagent grades?
The PRA (Pro Analysis) grade offers higher purity (99.8%) with stricter controls on impurities like water, acids, and aldehydes, making it suitable for analytical and high-precision applications, unlike technical grades used for general purposes.
