Diethyl Ether stabilized with BHT is a high-purity, anhydrous ether solvent widely used in peptide and oligonucleotide synthesis, as well as in preparative and analytical procedures in pharmaceutical and biochemical laboratories.
🏭⚗️ Production
The solvent is produced by distilling ethoxyethane to high purity and adding a small amount of the antioxidant stabilizer Butylated Hydroxytoluene (BHT) to prevent peroxide formation during storage and handling. The solution is packaged in sealed, light-resistant containers under dry and inert conditions to maintain its anhydrous and stabilized status for safe use in regulated laboratory environments.
🔬 Properties
Diethyl ether stabilized with BHT is a clear, colorless liquid with a low boiling point and low density. It is fully miscible with many organic solvents and has limited solubility in water. The addition of BHT significantly reduces the risk of peroxide formation, though the solvent remains highly sensitive to air, light, heat, and strong oxidizers. The solvent is volatile, highly flammable, and must be handled carefully to maintain its purity and reactivity.
🧪 Applications
In pharmaceutical and analytical laboratories, this solvent is used for precipitation or washing steps in peptide synthesis workflows, extraction and work-up steps in oligonucleotide synthesis, and as a low UV-absorption solvent in preparative chromatography. It also serves as a general-purpose, non-polar, volatile solvent for reactions and purification steps where a stable ether is required. The BHT stabilization ensures safer storage and reproducible results in sensitive laboratory procedures.
⚠️ Safety
Diethyl ether stabilized with BHT is highly flammable and can form explosive peroxides if stored improperly. It should be handled under strict laboratory safety protocols, including wearing gloves, protective eyewear, and lab coats, and working in a well-ventilated fume hood. Containers should be stored in a cool, dry place, tightly sealed, and protected from air, light, heat, and ignition sources. Waste and empty containers must be disposed of according to laboratory hazardous waste regulations.
