SP-Merrifield High Loaded Resin, MP
PRODUCT:
SP-Merrifield High Loaded Resin, MP, a highly cross-linked polystyrene resin functionalized with a chloromethyl end group.
 
APPLICATIONS:
  • SP-Merrifield High Loaded Resin is a chloromethyl functional resin that can be used for direct immobilization of carboxylic acids including N-protected amino acids.
  • SP-Merrifield High Loaded Resin may be employed as a linker for secondary amines and as a base resin to incorporate linkers using easy loading of phenols and thiophenols.
  • A simple, highly effective method for removing triphenylphosphine and/or triphenylphosphine oxide from reaction mixtures with high-loading chloromethylated polystyrene, modified in situ with NaI, acts as a scavenger resin.
  • SP-Merrifield High Loaded Resin has a highly cross-linked macroporous resin framework, hence it is not dependent on swelling to be effective, making it compatible with a broad range of solvents including highly polar solvents including DMF and acetonitrile.
PROPERTIES:
Resin Type:   Macroporous poly(styrene-co-divinylbenzene)
Loading:        3.8-4.1 mmol/g (based on chlorine analysis)
Bead Size:     330-1225 microns, 15-48 mesh (>90% within)
Compatible Solvents:  DCM, DMF, THF, MeOH, and acetonitrile.
