Abstract

Abstract: Clindamycin phosphate, an antibiotic drug, was used extensively in clinic. In this study, the ¹H, ¹³C and ³¹P chemical shifts of the compound were assigned using 2D NMR techniques, including DEPT, ¹H-¹H COSY, ¹³C-¹H HSQC and ¹³C-¹H HMBC. The relative stereochemistry was established by the results obtained from quantum chemical calculation and NOESY spectroscopy. The fragmentation pathway of clindamycin phosphate was also analyzed by TOF-MS/MS.

Key words: NMR, clindamycin phosphate, chemical shift assignment, TOF-MS
