Chemical Structure
Description
CATO supplies Pimobendan Impurity 15-d3 (CAS CATO-C4X-246116), a pharmacopoeial impurity reference standard (molecular formula C19H15D3N4O2, MW 337.39 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Pimobendan Impurity 15-d3 (C19H15D3N4O2) is characterized by deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), Pimobendan Impurity 15-d3 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.
