Chemical Structure
Description
The occurrence of Goserelin Impurity 25 Acetate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Goserelin Impurity 25 Acetate (CAS CATO-C4X-192025), a pharmacopoeial impurity reference standard (molecular formula C25H48N10O6C2H4O2, MW 644.77 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C25H48N10O6C2H4O2, Goserelin Impurity 25 Acetate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 644.77 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), Goserelin Impurity 25 Acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
