Chemical Structure
Description
The occurrence of Mometasone Furoate EP Impurity N is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Mometasone Furoate EP Impurity N (CAS 352315-75-4), a pharmacopoeial impurity reference standard (molecular formula C23H31ClO7S, MW 487.01 g/mol) used for the identification and quantification of trace impurities in APIs.
Mometasone Furoate EP Impurity N (C23H31ClO7S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Mometasone Furoate EP Impurity N 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.
