It is also used to prepare N,N-diisopropylethylamine (Hünig's base) by alkylation with diethyl sulfate. [8] The bromide salt of diisopropylamine, diisopropylammonium bromide, is a room-temperature organic ferroelectric material. [9]
A variety of amines and nitrogen heterocycles are useful bases of moderate strength (pK a of conjugate acid around 10-13) . N,N-Diisopropylethylamine (DIPEA, also called Hünig's Base [1]), pK a = 10.75

HATU (Hexafluorophosphate Azabenzotriazole Tetramethyl Uronium) is a reagent used in peptide coupling chemistry to generate an active ester from a carboxylic acid. HATU is used along with Hünig's base (N,N-diisopropylethylamine), or triethylamine to form amide bonds.
Inhalation and skin contact are expected to be the primary ways of occupational exposure to this chemical. Based on single exposure animal tests, it is considered to be slightly toxic if swallowed or inhaled, moderately toxic if absorbed through skin as well as being corrosive to eyes and skin. [1]
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
