Vilazodone impurity 16 CAS 795266-89-6 chemical structure

Description

CATO supplies Vilazodone impurity 16 (CAS 795266-89-6), a pharmacopoeial impurity reference standard (molecular formula C25H26N4O, MW 398.50 g/mol) used for the identification and quantification of trace impurities in APIs.

Vilazodone impurity 16 (C25H26N4O) contains a steroid core, 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.

CATO manufactures Vilazodone impurity 16 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.
