Chemical Structure
Description
The occurrence of Zolmitriptan Impurity 36 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Zolmitriptan Impurity 36 (CAS CATO-C4X-135136), a pharmacopoeial impurity reference standard (molecular formula C17H24N3O3I, MW 445.30 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, Zolmitriptan Impurity 36 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 445.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Zolmitriptan Impurity 36 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.
