Maropitant Impurity 13 CAS 155681-48-4 chemical structure

Description

As a certified reference material (CRM), Maropitant Impurity 13 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.

CATO supplies Maropitant Impurity 13 (CAS 155681-48-4), a pharmacopoeial impurity reference standard (molecular formula C27H30N2, MW 382.54 g/mol) used for the identification and quantification of trace impurities in APIs.

Maropitant Impurity 13 (C27H30N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
