Zolmitriptan Impurity 33 Iodide (Mixture of Diastereomers) CAS CATO-C4X-135133 chemical structure

Description

CATO manufactures Zolmitriptan Impurity 33 Iodide (Mixture of Diastereomers) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

As a process- or degradation-related impurity, Zolmitriptan Impurity 33 Iodide (Mixture of Diastereomers) (CAS CATO-C4X-135133, C16H22N3O3I) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, Zolmitriptan Impurity 33 Iodide (Mixture of Diastereomers) (C16H22N3O3I) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 431.27 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
