Product Details
Diisopropylamine is a secondary amine that appears as a colorless liquid at room temperature, featuring a fishy, ammonia‑like odor. It serves as a key chemical intermediate and catalyst in the production of pesticides and pharmaleic-anhydride.html">maceuticals. Diisopropylamine may be present in tobacco as a natural constituent, a pyrolysis product in tobacco smoke, or an additive in certain tobacco products. Common alternative names include DIPA and N-(1-methylethyl)-2-propanamine.

Product Application Of Diisopropylamine CAS#108-18-9
Diisopropylamine is widely used as a solvent and in organic synthesis for manufacturing dyes, pharmaceuticals, and various fine chemicals. It is a critical building block for synthesizing diisopropylamine methyl urea (DMU), N,N-diisopropyl quinoline-2-carboxamide, 3-N-sulfonylamidine coumarins, and N-chloroamine, which act as intermediates for amide production.
