Chemical Structure
Description
CATO supplies Ticagrelor Impurity 73 D-Tartrate (CAS CATO-C4X-109373), a pharmacopoeial impurity reference standard (molecular formula C12H21NO5C4H6O6, MW 409.39 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Ticagrelor Impurity 73 D-Tartrate (C12H21NO5C4H6O6) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
