2,3,4,6-Tetra-O-acetyl-alpha-D-galactopyranosyl bromide Chemical Properties,Usage,Production

  • Chemical Properties White Crystalline Solid
  • Uses Temperature and moisture sensitive; Store in freezer; Stabilized with 2% CaCO3
  • Purification Methods Purify acetobromo-D-galactose as for the glucose analogue (next entry). If the compound melts lower than 87o or is highly coloured, then dissolve it in CHCl3 (ca 3 volumes) and extract with H2O (2 volumes), 5% aqueous NaHCO3, and again with H2O and dry it over Na2SO4. Filter and evaporate it in a vacuum. The partially crystalline solid or syrup is dissolved in dry Et2O (must be very dry) and recrystallised by adding pet ether (b 40-60o) to give a white product.
