1. Fundamental Identifiers
IUPAC Name: 2-(Propan-2-yloxy)propane / Diisopropyl ether
Common Names:
Isopropyl ether
Diisopropyl ether (DIPE)
CAS Registry Number: 108-20-3
EC Number: 203-560-6
UN Number: 1159
Molecular Weight: 102.18 g/mol
2. Structural & Chemical Profile
Chemical Class: Symmetrical dialkyl ether.
Key Characteristics:
Excellent Solvent: A low-polarity, aprotic solvent with good solvating power for many organic compounds.
Low Boiling Point: Volatile liquid.
Notorious Hazard: Extremely prone to form explosive organic peroxides upon prolonged exposure to air and light. This is its defining and most critical safety concern.

1. Solvent & Extraction Agent:
Use: Extraction of fats, oils, waxes, and natural products (e.g., in pharmaceuticals). Now largely replaced due to safety concerns.
2. Reaction Solvent:
Use: For Grignard reactions and other organometallic syntheses. Superseded by safer alternatives like tetrahydrofuran (THF).
3. Fuel Additive (Historical):
Use: As an octane booster in gasoline. Completely phased out for safety and environmental reasons.
4. Aviation Starting Fluid (Limited, Historical):
Use: To aid in starting aircraft engines in cold weather. Rarely used today.
5. Laboratory Reagent (with Extreme Caution):
Use: In specific, controlled laboratory procedures where its properties are uniquely required. Requires strict peroxide management.
