Description
CATO supplies Goserelin Impurity 26 Acetate (CAS 52434-75-0(free base)), a pharmacopoeial impurity reference standard (molecular formula C34H38N8O9C2H4O2, MW 762.78 g/mol) used for the identification and quantification of trace impurities in APIs.
Goserelin Impurity 26 Acetate (C34H38N8O9C2H4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
