Chemical Structure

Ledipasvir Impurity 7 CAS CATO-C4X-33137 chemical structure

Description

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.

CATO supplies Ledipasvir Impurity 7 (CAS CATO-C4X-33137), a pharmacopoeial impurity reference standard (molecular formula C9H17NO4, MW 203.24 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Ledipasvir Impurity 7 (C9H17NO4) is characterized by an amino-acid-derived structure, 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.

As a certified reference material (CRM), Ledipasvir Impurity 7 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.
