O. Pietraszkiewicz et M. Pietraszkiewicz, SEPARATION OF PYRIMIDINE-BASES ON HPLC STATIONARY RP-18 PHASE COATED WITH CALIX[4]RESORCINARENE, Polish Journal of Chemistry, 72(11), 1998, pp. 2418-2422
The calix[4]resorcinarene-coated RP-18 phases were found to be useful
beds for HPLC separation of thymine, cytosine and uracil. Typical lipo
philic calix[4] resorcinarene prepared from lauryl aldehyde and resorc
inol was used.
