DIPEA is a sterically hindered organic base that is commonly employed as a proton scavenger. Thus, like 2,2,6,6-tetramethylpiperidine and triethylamine, DIPEA is a good base but a poor nucleophile, DIPEA has low solubility in water, which makes it very easily recovered in commercial processes, a combination of properties that makes it a useful organic reagent. regaly ramoweWebN,N-Diisopropylethylamine, 99.5+%, Thermo Scientific Chemicals Fisher Scientific Account Basket Structure Search Print SDS N,N-Diisopropylethylamine, 99.5+%, … probiotic greenlifeWebActive esters generated with most commonly used coupling reagents.
