Product Overview
Diisopropyl Ether ARS, ACS is a high-purity laboratory solvent engineered for critical applications requiring exceptional consistency and minimal impurities. This analytical reagent-grade ether meets stringent ACS specifications, ensuring 99%+ purity with controlled peroxide levels below 0.005%. The solvent’s low water content (<0.05%) and neutral pH make it particularly suitable for moisture-sensitive reactions and extraction processes where solvent purity directly impacts experimental outcomes. Its excellent solvency power for nonpolar compounds combined with a relatively low boiling point (68°C) allows for efficient evaporation during sample preparation. The ARS certification guarantees batch-to-batch consistency, while the ACS designation confirms compliance with American Chemical Society standards for reagent chemicals. Packaged in amber glass bottles to prevent photodegradation, this ether maintains stability during storage and transportation. The solvent's low viscosity and high volatility profile enable precise dispensing and rapid drying in analytical procedures. Each batch undergoes rigorous GC-MS analysis to verify the absence of common contaminants like alcohols, ketones, or peroxides that could interfere with sensitive applications.
FAQs
1. What is the maximum allowable peroxide content in this Diisopropyl Ether?
The peroxide content is strictly controlled below 0.005% as per ACS specifications, with each batch tested before release.
2. Can this ether be used with lithium aluminum hydride reactions?
While chemically compatible, the low peroxide content makes it safer for such reactions, though standard precautions for ether use with strong reducing agents should be followed.
3. What alternative solvents offer similar polarity but higher flash points?
Methyl tert-butyl ether (MTBE) provides comparable polarity with a higher flash point (-28°C vs -22°C for diisopropyl ether) while maintaining good solvency.
4. How should unused portions be stored to maintain purity?
Store in the original amber glass bottle with a tight PTFE-lined cap at 15-25°C, away from direct light and ignition sources. Add molecular sieves to prevent moisture absorption.
5. What analytical methods verify the purity of this grade?
Each batch is analyzed using GC-MS for volatile impurities, Karl Fischer titration for water content, and iodometric titration for peroxide determination as per ACS protocols.
