Bicine → Glycine, N,N-bis(2-hydroxyethyl)-, sodium salt (1:1)

Participants

Reaction Steps

N,N-Bis-(2-hydroxyethyl)aminoacetic acid (364.933 grams, 2.2144 moles) (this material is 99% pure; it contains 1% or 3.613 grams of H2O) is added with stirring to a cooled solution of pure sodium hydroxide (88.57 grams, 2.2144 moles) in pyrogen-free distilled water (400 ml.). The mixture is stirred until solution is effected. After reaching room temperature, the solution is stirred while enough pyrogen-free distilled water is added to make the total volume 1,000 ml. The solution is sterilized by filtration. This solution is 41% or 2.2144 molar in sodium N,N-bis-(2-hydroxyethyl)aminoacetate.
