Diisopropylethylamine for Peptide Synthesis

Diisopropylethylamine (DIPEA) is a commonly used organic base in peptide synthesis. It is a colourless liquid with the chemical formula (CH3)2CHCH2N(CH2CH3)2. DIPEA is a tertiary amine, which makes it a strong organic base with a pKa of approximately 11. It is often used as a nucleophilic catalyst to promote peptide bond formation during solid-phase peptide synthesis (SPPS).

DIPEA is highly purified and free of impurities that may interfere with peptide synthesis reactions. It is compatible with a wide range of peptide synthesis protocols and can be used in various coupling reagents and solvents. DIPEA is also used in other chemical reactions, such as in the synthesis of polymers, drugs, and natural products.

Overall, DIPEA is an important reagent in peptide synthesis and organic chemistry due to its strong basicity, low nucleophilicity, and compatibility with various solvents and coupling reagents.
