Chemical Structure
Description
riptorelin Impurity 21 ·xTFA salt (C59H77N17O11·x(C2HF3O2)) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
riptorelin Impurity 21 ·xTFA salt (CAS CATO-C4X-186222) is a certified pharmaceutical impurity reference standard with the molecular formula C59H77N17O11·x(C2HF3O2) and a molecular weight of 1314.39 g/mol.
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.
