Chemical Structure

Ribociclib Impurity 14 CAS 1331847-17-6 chemical structure

Description

As a certified reference material (CRM), Ribociclib Impurity 14 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 Ribociclib Impurity 14 (CAS 1331847-17-6), a pharmacopoeial impurity reference standard (molecular formula C14H19N5O, MW 273.33 g/mol) used for the identification and quantification of trace impurities in APIs.

Ribociclib Impurity 14 (C14H19N5O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.
