General description

Diglycolyl chloride (2,2′-Oxydiacetyl chloride) is an acid halide.

Application

Diglycolyl chloride is suitable for use in the synthesis of ply(ether ester). It may be used in the synthesis of:
  • chiral diphenyl substituted polyether-diester compounds
  • morpholine dione analog (IMDNQ)
  • salicylic acid (SA)- based diacids
Diglycolyl chloride may be used in the synthesis of the following compounds:
  • diazadibenzo-18-crown-6 diamide
  • diazadi(tert-butylbenzo)-18-crown-6 diamide
  • surfen derivative
