Chemical Structure
Description
The molecular framework of (2|A,3|A,5|A,14xi,22r)-2,3,14,25-tetrahydroxy-6-oxocholest-7-en-22-yl dihydrogen phosphate 868-26-8 KST-1A8639 (C5H7BrO4) is characterized by a carbohydrate-derived structure, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
