Product Overview
Diethylamine is a high-purity secondary amine widely used as a building block in organic synthesis, pharmaceutical intermediates, and specialty chemical manufacturing. This lab-grade reagent, supplied at 99% purity, offers excellent reactivity as a strong organic base, nucleophile, and solvent for polar and non-polar compounds. Its hygroscopic nature requires careful handling under inert conditions to prevent moisture absorption, which can affect reaction stoichiometry. The liquid form ensures easy dispensability in titration, extraction, and catalytic processes, while its miscibility with common organic solvents like ethanol, ether, and hydrocarbons enhances versatility in multi-step syntheses. The product is stabilized to minimize oxidative degradation, ensuring consistent performance in amine alkylation, acylation, and condensation reactions. Its low boiling point (55–57°C) facilitates straightforward purification via distillation, making it ideal for high-precision lab applications. Supplied in airtight, chemical-resistant packaging, this Diethylamine variant meets stringent quality controls for reproducibility in research and industrial-scale processes.
FAQs
1. What is the shelf life of Diethylamine when stored properly?
When stored in a tightly sealed container under cool, dry conditions away from moisture and oxidizing agents, Diethylamine retains its specified purity for up to 24 months from the date of manufacture. Prolonged exposure to air or humidity may lead to amine oxidation or carbonate formation.
2. Is this Diethylamine compatible with glass or plastic labware?
Diethylamine is compatible with borosilicate glass and high-density polyethylene (HDPE) containers. Avoid prolonged contact with soft plastics, rubber, or metals like copper and zinc, as it may cause degradation or leaching. For storage, use glass bottles with PTFE-lined caps.
3. Can Diethylamine be used as a substitute for Triethylamine in reactions?
While both are secondary amines, Diethylamine is a stronger base (pKa ~11.0) compared to Triethylamine (pKa ~10.7) and may exhibit different steric and electronic effects in reactions. Substitution depends on the specific mechanism—test compatibility in small-scale trials before full replacement.
4. What precautions should be taken during handling to prevent contamination?
Use Diethylamine in a fume hood with proper ventilation, as it emits pungent, irritating vapors. Wear nitrile gloves, safety goggles, and a lab coat to avoid skin or eye contact. Dispense using a dry syringe or pipette, and avoid breathing dust or mist. Neutralize spills with dilute acetic acid.
5. How does the purity of this Diethylamine compare to technical-grade variants?
This 99% pure lab-grade Diethylamine undergoes rigorous distillation and quality checks to remove impurities like water, primary/tertiary amines, and heavy metals. Technical-grade variants (typically 90–95% pure) may contain residual solvents or byproducts, affecting reaction yields and reproducibility.
