Product Overview
Diisopropylamine, 99.5% redistilled, represents a high-purity secondary amine designed for demanding laboratory applications where moisture sensitivity and reagent quality are critical. This AcroSeal®-packaged chemical undergoes rigorous redistillation to eliminate trace impurities, ensuring consistent performance in organic synthesis and specialty chemical processes. The compound’s sterically hindered structure provides unique reactivity profiles compared to primary amines, making it particularly valuable for selective transformations. Its relatively high boiling point (83-84°C) allows for easier handling in reflux conditions while maintaining volatility for purification steps. The AcroSeal® packaging system preserves the reagent’s integrity by minimizing exposure to atmospheric moisture and oxygen, extending shelf life and maintaining purity specifications. This grade meets stringent quality control standards, with residual water content typically below 0.05% and negligible levels of primary/tertiary amine impurities. The clear, colorless liquid offers excellent solubility in most organic solvents while maintaining stability under standard storage conditions.
FAQs
1. What is the difference between redistilled and standard-grade Diisopropylamine?
The redistilled grade undergoes additional purification through fractional distillation, removing trace impurities like water, primary amines, and oxidation products that may be present in standard grades. This results in higher purity (99.5% minimum) and more consistent performance in sensitive reactions.
2. Can this product be used directly without further purification?
While the 99.5% redistilled grade meets most laboratory requirements, some ultra-sensitive applications may benefit from additional drying with molecular sieves or brief distillation under inert atmosphere to achieve maximum purity.
3. What precautions should be taken when handling Diisopropylamine?
Always handle in a well-ventilated fume hood due to its pungent odor and potential respiratory irritation. Use nitrile gloves and safety goggles as the liquid can cause skin and eye irritation. The AcroSeal® packaging should be opened carefully to avoid pressure release.
4. How does the AcroSeal® packaging benefit this chemical?
The AcroSeal® system features a specialized septum and bottle design that minimizes air exposure during dispensing, reducing moisture absorption and oxidation. This preserves the reagent’s purity over extended storage periods compared to traditional packaging.
5. What is the typical shelf life under proper storage conditions?
When stored unopened in its original AcroSeal® packaging at room temperature (15-25°C), the product maintains its specified purity for at least 24 months from the date of manufacture. Opened containers should be resealed tightly and used within 6 months.
