N-Ethyldiisopropylamine
N-Ethyldiisopropylamine (CAS: 7087-68-5) is a sterically hindered, non-nucleophilic organic base with the linear formula CH3CH2N[CH(CH3)2]2 and a molecular weight of 129.24 g/mol. Commonly known as Hünig's base, it is widely utilised as an acid scavenger in organic synthesis. Its bulky nature prevents it from acting as a nucleophile, making it ideal for promoting reactions without unwanted side products. It is supplied by TSS with an assay of ≥98.0%.

Acid Scavenger in Organic Synthesis
N-Ethyldiisopropylamine effectively neutralises acidic by-products generated during various organic reactions, such as alkylations, acylations, and silylations. Its steric hindrance prevents it from participating as a nucleophile, ensuring cleaner reaction profiles and higher yields of desired products.
Base in Elimination Reactions
This hindered amine can be employed to promote elimination reactions where a strong, non-nucleophilic base is required. It facilitates the removal of leaving groups without competing nucleophilic attack, crucial for synthesising specific olefins.
Protecting Group Chemistry
In complex multi-step syntheses, N-Ethyldiisopropylamine is used to facilitate the introduction and removal of protecting groups. Its basicity aids in the formation of silyl ethers and other protecting functionalities.
