Application
Polyethylene glycol diacid 600 can be used as an acylating agent as well as a solvent in the resolution of free secondary alcohols using a biocatalyst. It is also used as a hydrophilic ligand in the surface modification of lanthanide co-doped NaYF4 nanocrystals via ligand exchange reaction to impart the water solubility of the nanocrystals.
