WebThe ICH has published the limits of the residual solvents that considered safe in pharmaceutical preparations; also, it has published the daily exposure limits for these solvents. It has classified these solvents in three categories depending on their toxicity. DIPEA consists of a central nitrogen atom that is bonded to an ethyl group and two isopropyl groups. A lone pair of electrons resides on the nitrogen atom, which can react with electrophiles. However, as the two isopropyl groups and the ethyl group occupy much of the space surrounding the N atom, only small electrophiles such as protons can react with the nitrogen lone pair.
